摘　　要：基于投影空间,提出了频率选择性MIMO(FS-MIMO)信道下一种实现块传输的收发联合设计方案。通过收发联合分离多径,把选择性信道转化为了若干正交的平坦MIMO等效信道,增加了系统设计的自由度。给出了一种容量最优的功率分配方案,推导了其误码率和信道容量的解析式。仿真结果验证了理论分析的正确性,该方案在高信噪比时与非块传输相比容量增益为L(多径数目)。Based on orthogonal projection,a transceiver scheme is proposed for MIMO block transmission over frequency-selective channel.By separating multi-path components,the selective MIMO channel is decomposed into L（the number of multi-path components） flat orthogonal MIMO effective channels,increasing degrees of freedom of system design.The analytical expressions of BER and capacity are given,based on proposed capacity-optimal power allocation.Simulation results show that compared with the existing non-block transmission,the capacity gain is L in high SNR regime.
