- Abstract:
- Space-time coding can provide high data rate and performance gain for wireless communication system. Performance comparison of space-time trellis codes and space-time transmit diversity is carried out under the same bandwidth efficiency in this paper. We also propose some optimum low rate space-time trellis codes in quasi-static Rayleigh fading chan￣nel. Performance analysis and simulation show that the low rate space-time trellis codes outperform space-time transmit diversity at the same bandwidth efficiency, and are more suitable for the power limited wireless communication system which has no strict requirement on bandwidth efficiency.
- 空时编码能够为无线通信系统提供高数据速率及性能.本文在相同频带利用率下将空时格码与空时发射分集的性能进行了比较.同时, 针对准静态瑞利衰落信道, 提出了几种优化的低码率空时格码.理论分析和仿真表明, 在相同的频带利用率下, 该低码率空时网格码可具有比空时发射分集更好的误码率性能, 更适合于对频带利用率要求不高的功率受限无线通信系统.
