Space Time Turbo Coded Ofdm System With Transmit and Receive Antenna Selection

Abstract

In this paper a space-time turbo coded (STTC) orthogonal frequency division multiplexing (OFDM) system with QPSK signalling is explored when joint transmit and receive antenna selection is employed. Maximization of signal to noise ratio is used for antenna selection based on per-tone all-tone or hybrid selection criteria. Simulation results show that applying joint transmit/receive antenna selection techniques for STTC-OFDM systems can improve error rate performances considerably by achieving high diversity orders thus make it preferable for standards of high speed wireless networks. © 2011 Chamber of Turkish Electric.
