Then this paper makes some overview and simulation on the application of three precoding algorithms under the flat fading channel , which are linear preequalization , tomlinson - harashima precoding ( thp ) and lattice reduction - aided ( lll ) vector precoding 本文對三種常見的預編碼算法在平坦衰落信道下的應用進行了綜述和仿真研究,包括迫零線性預均衡、 thp預編碼和格約簡輔助矢量預編碼等算法。
