Abstract This paper firstly analyzes the eigenvalue distribution in environment with different angle spread and DOA. Secondly, the performance of different beamforming algorithms are investigated first in diverse environment. Then a beamforming scheme based on eigenvalue distribution is proposed, which can adaptively utilize different beamforming algorithm according to the eigenvalue distribution. Simulation results show that the proposed method possesses almost the same performance as the Per-Path Per-Weight(PPPW) beamforming method, furthermore the complexity is reduced greatly.
