A compact multiband pattern diversity antenna for Multiple input multiple output (MIMO) applications is being proposed. The pattern diversity antenna is designed for 2.6 GHz LTE, 3.5/5.5 GHz WiMax, 3.3 GHz MIMO and 5.2 GHz WLAN applications for mobile devices. The compact size of the MIMO antenna (41.05 × 21.1 mm) is due to having compact individual monopole antennas each of dimension 17.5 × 10 mm. A T-shaped and inverted L-shaped stub in the ground plane reduces mutual coupling due to near field whereas slots introduced in the ground plane prevents current to flow through the common ground plane. The important characteristics of MIMO antenna like diversity gain and envelope correlation coefficient have also been presented. Measured and simulated radiation patterns presented show that the MIMO antenna proposed provide pattern diversity.

Smart antenna attempt to enhance the received signal, suppress all interfering signals, and increase capacity. Beamforming is one of the mostly used antenna technique. It adjust the radiation beam in one specific direction also reduces multiple access interference. It also reduces common channel interference and multiple path fading, in result it increases capacity of mobile network. In this paper two antenna beam forming algorithms are analyzed. These two algorithms are Least Mean Square and Minimum Variance Distortionless Response. Outputs of these two algorithms are in weights. By using these outputs weights, two parameters i.e. Mean Square Error and Power Beam Width are calculated and two algorithm are compared by this parameters and respective results are discussed.

Analysis of minimum variance distortionless response and least mean square beamforming algorithm for smart antenna

In recent years due to globalization and increase in competition to capture market share, the customer is having many options of cars at much affordable prices .This has led to tremendous amount of cars on the road. The big cities in India are normally crowded and the city's existing infrastructure falls short to satisfy the growing needs. This problem is also combined with the inefficient use of parking space and uneven distribution of traffic which leads to congestion in vehicular traffic. This paper introduces a novel technique based on Internet of Things platform to improve efficiency of the existing parking systems. It guides driver to find nearest parking slots. The prototype uses cloud based architecture of Internet of things. There is minimum delay in finding an optimal parking slot which helps to ease the traffic congestion. The proposed system also helps users automatically find a free parking space at the smallest distance based on Haversine formula if nearest parking region is full.

A smart antenna is actually a fusion of an array that changes individual antenna elements patterns in response of a dedicated signal to improve performance. Moving one step beyond of beam forming is adaptive algorithm which allows for the computation of continuously amend weights. The process of adaptation must satisfy a specified optimization principle. In this project two Adaptive algorithm Least Mean Square and Recursive Least Mean Square are implemented to revamp beam. Added optimization of beam is accomplished with the help of genetic algorithm which makes beam more optimize. This optimization method is used for the synthesis of antenna array radiation pattern in adaptive beam forming. The optimum value of weights of each antenna element is determined which produces a radiation pattern with minimum side lobe level. Analysis is being carried out with varying different element and space in between element to obtain the minimum weight with the help of genetic algorithm. This improves the performance to achieve the maximum reduction in side lobe level (of the order -20dB) with minimum function calls.

The prediction of Indian summer monsoon (ISM) variability on extended range (3-4 pentads in advance, where pentad refers to 5-day average) is crucial due to its usefulness in agricultural and hydrological planning. Monsoon rainfall occurs in the form of active/break spells which causes large-scale flood/drought condition. Prediction before 3-4 pentad may not stop this condition but can help us to prepare for the same. Hence Climate Forecast System model version 2 (CFSv2) has been adopted to develop a dynamical prediction system for monsoon rainfall on different time scales. The Extended Range Prediction (ERP) group at Indian Institute of Tropical Meteorology has indigenously developed an Ensemble Prediction System based on CFSv2 for the real-Time prediction of active/break spells of ISM and has been providing the experimental forecasts up to 4 pentad lead. A multi-model ensemble (MME) framework employing different variants of CFSv2 has shown better skill in the ERP of ISM, compared to the individual variants. Still CFSv2 model shows statistical biases which cause lack of skill in MME and causes false prediction. In this study, it is proposed to employ the artificial neural network based technique to reduce the inherent biases by post-processing the raw model output. The performance is evaluated with mean square error, correlation coordinate and Brier skill score. Result shows that the probabilistic skill of the model is improved with the ANN- based technique.

Comparative Analysis of MVDR & RLS Beamforming Algorithm for Smart Antenna

Power Systems suffer from various types of faults such as Phase and Earth Faults. These faults lead to overcurrent in the circuits. Numerical Relays embedded with Digital Signal Processor (DSP) can be used to protect the system components as they can perform complex processing faster with higher accuracy and also avoid problem of false tripping. DSP based processing can also be optimized for real time. In this paper, TMS320F28335 based Implementation of Numerical Relay is discussed. TMS320F28335 is a floating point Digital Signal Controller (DSC). Short Time Fourier Transform (STFT) is used to detect the spurious signals and faults more accurately. The proposed overcurrent protection system is implemented on real time basis with the help of AntiAliasing filter and Signal Conditioning Circuit to scale the inputs from Current Transformer. Anti-Aliasing filter is designed based on the fault current simulation data generated using Power System Simulation Software. Fault current patterns generated are analyzed by calculating Fourier Transform coefficients that decide the filter specifications. Code Composer Studio (CCS) IDE is used for the development of algorithm. The paper discusses development of overcurrent protection algorithm based on RMS calculation for single phase circuits using TMS320F28335. The overcurrent relay Inverse Definite Minimum Time (IDMT) characteristics curves based on the simulated fault current data are used as basis and are implemented for Single Phase Circuits. © 2014 IEEE.

Numerical results obtained by directly applying the perfectly-matched layer (PML) to an open boundary problem, i.e. the calculation of PCB crosstalk using the TLM, are presented. While evanescent waves cannot be absorbed even by a large number of PML layers, a single layer is sufficient provided it is placed sufficiently far away.

The transmission-line-matrix (TLM) numerical time-domain method using the symmetrical super-condensed node (SSCN) is applied to calculate the cross-talk time & frequency-response between tracks on a double-sided Vertical-PCB-on-backplane configuration over a frequency range of 50 MHz to 1 GHz. Meshing was done on a layer-wise basis which consisted of dividing the entire computational region into groups-of-vertical-layers in the XY plane, with each group of layers having the same mesh pattern. Extensive use was made of a recently introduced one and two dimensional multi-gridding technique to keep the total mesh count to a reasonable value. Perfectly-matched-layer absorbing boundary conditions were used and simulation was done for six PCB configurations for 100,000 time-steps, the time-step being 0.523 ps for a spatial resolution of 0.3175 mm. Simulation results compare well with the experimental data over the frequency range of interest.

Modelling of PCB cross-talk using the transmission-line-matrix(TLM) method

This paper extends Wlodarcyzk's TLM multi-gridding-technique to the generalized one and two dimensional cases wherein the fine meshes can have different lengths and widths. The advantage is that it is no longer necessary to divide the problem space into separate 'coarse' and 'fine' regions which provides for considerable meshing flexibility. Equations describing the connection procedure for the SSCN are derived. Modelling of cross-talk between PCB tracks is implemented with this new method and the simulation results compared with experiments.
