【 摘 要 】

The model of 3D multiple input multiple output and orthogonal frequency division multiplexing(MIMO-OFDM) system was introduced,and the channel estimation scheme based on pilot was analyzed.In view of the problem of high complexity of the linear least mean square error algorithm,the singular value decomposition(SVD) algorithm was proposed and applied to reduce the dimension of channel autocorrelation matrix,thus reducing computational complexity.The simulation results showed that the proposed channel estimation algorithm based on singular value decomposition could maintain the bit error rate(BER) performance with lower computational complexity.
