对高数据速率和编码增益的需求已经引起了人们对编码调制方案的极大兴趣。网格编码调制（TCM）是一种将编码和调制相结合，实现高编码增益的带宽有效传输方案。空时网格编码将信道编码与多个发射天线和多个接收天线相结合，以在衰落信道上实现带宽和功率有效的高数据速率传输。为了提高无线网络的带宽利用率，提出了超相移键控空时网格编码调制（HPSK ST-TCM）的设计方案。对于相同的每比特能量与噪声功率谱密度比，HPSK提供了与其他调制方案相当的误差性能的改进。
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.
