摘要
Abstract
In comparison with traditional multiple-input multiple-output( MIMO) systems,the number of antennas of massive MIMO increases significantly,which improves the system capacity and reduces the bit error rate( BER) but causes high precoding matrix dimension,precoding algorithm complexity,system cost and implementation difficulty. This paper classifies precoding technologies used in massive MIMO systems to two types, linear algorithms and nonlinear algorithms, summarizes and compares them with focuses on several simplified linear precoding algorithms and several typical nonlinear precoding algorithms. Finally,it points out that because of the high complexity of nonlinear algorithm, the future massive MIMO system should be based on linear precoding algorithms.关键词
