摘要
Abstract
The beamforming technique in cooperative multiple-input multiple-output( MIMO) system is presented. The amplify-forward and half-duplex mode is used in the relay transport protocol. A novel algorithm of singular value decomposition and minimum-mean-square error( SVD-MMSE) beamforming is proposed. The transmitting information using low-density parity-check code( LDPC) can effectively use spatial diversity to improve the system performance. Matlab simulation shows that the hybrid algorithm SVD-MMSE bit-error rate performance can respectively improve 0. 5 dB and 0. 4 dB at BER = 10 -6 than only SVD algorithm and MMSE algorithm.关键词
