The emerging need for high data rate and coding gain has raised considerable interest in coded modulation schemes. Trellis coded modulation (TCM) is a bandwidth efficient transmission scheme that can achieves high coding gain by integrating coding and modulation. Space-time trellis coding combines channel coding with multiple transmit and multiple receive antennas to achieve bandwidth and power efficient high data rate transmission over fading channels. This paper presents the design of hyper phase shift keying space-time trellis coded modulation (HPSK ST-TCM) for improving the bandwidth efficiency of wireless networks. HPSK offers an improvement in error performance comparable with other modulation schemes for the same energy per bit to noise power spectral density ratio.
