This paper proposes a method to select multi-antenna signals based on SNR estimation, in order to solve the negative influence of the poor partial quality branch signals in multi-antenna system. The algorithm proposes antenna selecting programs, based on the SNR estimation, the Cramer Rao bound and the combined signal matched filtering, to avoid the branch poor signals and enhance the signal combine quality. Theoretical and simulation results show that the proposed algorithm has a better performance than the traditional method, and the performance of the algorithm is improved with the increase of the number of antennas and the difference of the signal quality.
