摘要： This invention presents a repeater enhanced MU-MIMO wireless communication system comprising a BS, a plural of repeaters, and a plural of UEs, where a repeater estimates the channel between itself and its upper communication node in the system, a repeater computes equalization coefficients based on the estimation of the channel coefficients, and a repeater applies the equalization coefficients to reduce the channel delay spread or increase the coherence bandwidth of the channel between communication nodes containing the BS, the UEs, or the repeaters.
