Super-quasi-orthogonal space-time BPSK trellis coded OFDM system for four transmit antennas
Super-quasi-orthogonal space-time trellis codes (SQOSTTC) is a powerful code that provide full rate, full diversity and high coding gain for four transmit antennas. These codes, designed for flat fading channel combines set partitioning principle and a super set of quasi-orthogonal space-time block codes in a systematic way to provide full diversity and improved coding gain. In this paper, the performance of super-quasi-orthogonal space-time trellis coded orthogonal frequency division multiplexing system in frequency selective wideband wireless channel is investigated. A new 16 states BPSK code is proposed to avoid parallel transition that restricts the error performance of the code in frequency selective fading channel. Simulation results demonstrate the good performance of super-quasi-orthogonal space-time trellis coded OFDM system in a wideband channel.
