分布式无线通信系统中协同传输预编码方法研究

A coordinated transmission pre-coding method in distributed radio mobile communication system is proposed in this paper so as to improve the system receptivity which will drop along with deterioration of channel quality. Several remote antenna units (RAU) which are related to the receiver are processed jointly in this method. RAUs adopt different pre-coding rules to transmit data to one user according to channel state information. Terminal uses the joint processing approach to calculate the received signals which are transmitted by RAUs. Simulation experiment results show that the proposed method can effectively improve not only the bit error rate, but also the transmission reliability.
