Abstract

This paper analyzes the status quo of the precoding algorithm, and puts forward a power allocation mode called SINR, which has low computation complexity in the precoding relative to the water-filling power allocation. This algorithm obtains the precoding matrix by SVD singular value decomposition and uses SINR to realize the power allocation. Due to the avoidance of the iterative computation of the water flooding principle, the computational complexity of the power allocation is reduced. At the same time, the system and capacity and bit error rate have significantly improved over traditional average power allocation.
