Abstract
In distributed wireless communication and Coordinated Multi-Point(CoMP) system,the deterioration of channel quality seriously affect the system receptivity of edge users,and therefore the coordinated coding processing is used to improve the quality of reception.A coordinated transmission and joint pre-coding method was proposed in this paper.Coordinated Remote Antenna Units(RAU) were processed jointly.According to the state information of channel,different pre-coding rules were adopted by each RAU to transmit data to the same user.A Maximal-Ratio Combining(MRC) algorithm was used to calculate the received signals of terminals.The simulation results show that the proposed method can effectively decrease the Bit Error Rate(BER) and improve the transmission reliability.
