This paper focused on peak to average power ratio (PAPR) reduction scheme for OFDM system. OFDM has several properties which make it an attractive modulation scheme for high speed transmission. the main draw back of OFDM is high PAPR. The high PAPR causes the interference and degraded the performance of the system while OFDM signal pass through the amplifier. Here a simple scheme clip and filter is used to reduce the PAPR of OFDM system. Simulation results are show that the improvement in performance of OFDM system by reducing the PAPR using clip and filter scheme. (C) 2011 Published by Elsevier Ltd.

PAPR Reduction scheme For OFDM

This paper discusses the error performance of Space- Time Trellis Code system over fading channels. Multiple-input multiple-output (MIMO) technology constitutes a breakthrough in the design of wireless communications systems, and is already at the core of several wireless standards. It offers high data rate and excellent throughput of wireless communication system. Trellis-code modulation (TCM) is one of the bandwidth efficient coding modulation techniques used in digital communications system. Here we discuss the design criteria for fading channels, employs that transmit and receive antenna diversity. It is observed from the simulation results that the code performance is improved by increasing the number of states. Also it provided the coding advantage as the number of states and receives antennas increases. The simulation have been conducted for 4 Phase Shift Keying (PSK) with data rate 2 b/Hz/s for two transmit and two receive antennas (NT=NR=2) system, provided better performance using 64 states STTC encoder. © 2011 Springer-Verlag Berlin Heidelberg.

Performance analysis of MIMO- Space-Time trellis code system over fading channels

This paper discusses the performance analysis of multi-antennas systems with receive antenna selection over quasistatic fading channels. In performing the analysis with antenna selection, the selection criterion adopted is based on selecting best Nr antennas out of the available NR3 receive antennas such that the instantaneous signal-to-noise ratio (SNR) at the receiver is maximized. It is assumed that the total number of transmit antennas, NT =2, are equal to or greater than the total number of receive antennas. From the analysis it is shown that the resulting diversity order with antenna selection is maintained as that of full complexity system, however the coding gain deteriorates in proportion with reduced number of receive antennas. The results obtained with antenna selection with NR =2 and N R3 =3 multi-antenna systems are compared. © 2008 IEEE.

Performance analysis of space-time trellis codes with receive antenna selection

In this paper, orthogonal space-time block codes (OSTBC) are considered for investigating impact of receive antenna selection on the capacity and error probability analysis of multiple-input multiple-output (MIMO) systems. The results are compared with and without antenna selection of 2X2 and 2X4 MIMO systems. Achieved capacity with receive antenna selection for Nr ≥ NT has been found close to the capacity of full complexity system, whereas upper capacity bound is tight for Nr ≤ NT.

A reduced complexity MIMO system with antenna selection for high data rate wireless communications

Multi-Antenna systems allow for high data rates and improved quality of service but the cost paid for deriving these benefits is hardware complexity due to multiple antennas and the number of RF chains. Antenna selection techniques are proposed in recent time to reduce the hardware complexity to considerable extent, retaining the diversity benefits of Multiple-Input Multiple-Output (MIMO) systems. Space-Time coding schemes are the practical signal design techniques to realize the information theoretic capacity limits of MIMO systems. In this paper, orthogonal space-time block codes (OSTBC) are considered for the capacity and error probability analysis of MIMO systems with receive antenna selection. The numerical and simulation results obtained using MATLAB are presented for the channel capacity and bit-error probability in Rayleigh fading channels. The results are compared with and without antenna selection of space-time block coded MIMO system.

Capacity and performance analysis of space-time block coded MIMO systems with receive antenna selection in rayleigh fading channels

Multi-Antenna systems are expected to play very important role in future multimedia wireless communication systems. Such systems are predicted to provide tremendous improvement in spectrum utilization. In this paper we consider the capacity analysis of Multiple-Input Multiple-Output (MIMO) systems. Space-Time coding schemes are the practical signal design techniques to realize the information theoretic capacity limits of MIMO systems. Here the orthogonal space-time block codes are considered for the capacity and error probability analysis of MIMO systems as a case study. The numerical and simulation results obtained using MATLAB are presented for the Multi-antenna system channel capacity and bit-error probability in Rayleigh fading channels.
