本文提出了频率选择性瑞利衰落信道中的对角空频分组码(DSF)，研究了码的性能。
In this paper, we propose a diagonal space-frequency (DSF) block codes over frequency-selective Rayleigh fading channels and study performance of the code.
基于OFDM(正交频分复用)系统，提出了一种新的空频时三维编码，将网格编码调制和差分空时分组码进行组合链接设计。
Based on OFDM system, a novel space-frequency-time code which combined trellis-coded modulation with differential space-time block code was proposed.
