摘要：
We propose a quasioptimal method of separate optimization in a multistage relay MIMO system, which is based on optimization of the root-mean-square error between the input and output signals successively for each transmission stage. Rigorous analytical expressions for the spatial coding and decoding matrices are obtained. Separate optimization simplifies the system construction due to a significant reduction in the number of auxiliary (service) communication links, which are necessary for transmitting the channel information, compared with the joint optimization. The simulation results show the high efficiency of the proposed method.
