Layered differential space-time block code 分层结构差分空时分组编码
Different with the conventional STC, differential Space-time code can keep good performance when neither the transmitter nor the receiver knows the channel state information in Rayleigh flat fading channels.
与传统空时编码不同，差分空时编码不需要任何信道状态信息，在通信终端处于高速移动环境下的快速衰落信道中仍能保持较好的性能。
