In this paper, on LTE-A system based MIMO pre-coding codebook selection algorithm are researched. Traditional pre-coding selection algorithm requires to complete the corresponding code to traverse, however improved traversal algorithm are optimized than traditional traversal algorithms, but it has high complexity. Based on the stud-y of the two kinds of pre-coding selection algorithm, we propose a modified algorithm, then the algorithm in EPA5, EVA5, ETU70 on the type of channel simulation and analysis, Simulation results show that the algorithm performance with almost no loss compared with the traditional method, while significantly lower the complexity.
