Space-Time Block Coded-Joint Transmit/Receive Antenna Diversity Using More Than 4 Receive Antennas

Antenna diversity is an effective technique for improving the transmission performance in a multi-path fading channel. Recently, the authors proposed the Space-Time Block Coded-Joint Transmit/Receive antenna Diversity (STBC-JTRD), which allows the use of an arbitrary number of transmit antennas without sacrificing the coding rate. However, in STBC-JTRD, the number of receive antennas is limited to 4. In this paper, they show the STBC-JTRD encoding allowing the use of more than 5 receive antennas. The Bit Error Rate (BER) analysis in a frequency-nonselective Rayleigh fading channel is presented. The BER performance analysis is confirmed by computer simulation.
