摘要：

In order to solve the interference caused by the instability of the channel environment in Massive MIMO to the transmitted signal, this paper proposes a precoding method based on the channel condition number. In this algorithm, the channel condition number is used as the basis for judging the channel quality. Under different channel condition numbers, the transmit power is changed. At the same time, in order to reduce the hardware complexity, the algorithm uses Neumann series to replace the direct inversion of large-scale matrix, and choose the appropriate convergence factor, which can guarantee the convergence speed and reduce the number of iterations.
