Space Time Turbo Coded OFDM With Joint Transmit and Receive Antenna Selection
This paper discusses the performance of antenna selection technique in space time turbo coded MIMO-OFDM systems. Multiple-Input Multiple-Output (MIMO) technology can either increase the data rate through spatial multiplexing or improve the reliability through diversity. Space-Time Turbo Codes (STTC) have been proposed to provide robust communications in MIMO wireless environment. STTC technique incorporates the methods of transmitter diversity and channel coding to provide significant reduction of error rates over the traditional communication systems. The Orthogonal Frequency Division Multiplexing (OFDM) is a modulation method designed to mitigate multipath distortion and frequency selectivity of wireless channels at high data-rate transmissions.
