摘要 针对MIMO-OFDM系统,提出了一种低复杂度的基于多径时延跟踪的信道估计算法,并分析了信道估计的均方误差和计算复杂度.分析和仿真结果表明,这种算法通过对多径的跟踪降低了需要估计参数的维数,从而提高了信道估计的性能,并且降低了运算复杂度. A low complexity channel estimation algorithm based on the tracking of multipath time delays is presented for broadband multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. The estimator's performance and computation complexity is analyzed. Simulation results show that the tracking of multipath time delays can improve the channel estimation performance and reduce the computation complexity by decreasing the dimension of estimated parameters.
