Abstract

Signal to leakage and noise ratio (SLNR) based precoding algorithm is widely researched in CoMP-JP system. Nevertheless, the equivalent channel gain for each stream can be severely unbalanced in multi-stream transmission, and the overall performance is limited by the worst data stream. An improved SLNR based precoding algorithm is presented, which generates new precoding matrix with the method of weighting and linear transformation based on original SLNR vectors to eliminate the disparity of performance among streams, and optimize overall performance in multi-stream system. The simulation results demonstrate that our proposed algorithm can achieve considerable gains in error performance over the original SLNR and eliminate co-channel interference (CCI) among UEs at the same time for multi-stream transmission.
