摘    要:针对4根发射天线的宽带无线通信系统,提出一种两路复用的单载波空时分组编码方案.每一路信号均利用2根发射天线并采用满速率的正交空时分组码.本编码方案的码率为2,且只要求信道在两个连续的块内保持恒定.在接收端需要2根接收天线以分离两路空时编码信号,采用的干扰抵消和频域均衡算法具有较低的计算复杂度,且两路信号的检测均实现了满发射分集增益.

关 键 词:发射分集  空时分组编码  单载波频域均衡  干扰抵消

Abstract:For broadband wireless communication systems with 4 transmitting antennas,a two-stream multiplexed space-time block-coding scheme is proposed.Each stream employs two transmitting antennas and adopts full-rate orthogonal space-time block coding.The proposed coding scheme achieves a code rate of 2 and requires the channels to be stationary over only two consecutive blocks.Two antennas are needed at the receiver to separate the two space-time block coded streams.Interference cancellation and frequency-domain equalization at the receiver have low complexity while offering full transmission diversity gain for both streams.
Keywords:space-time block coding(STBC)  transmit diversity  single-carrier frequency-domain equalization(SC-FDE)  interference cancellation
