摘要：A method for processing user symbols with Tomlinson Harashima precoder

(THP) in a base station, of a wireless system having K user terminals (UEs) which

communicate with the base station via an uplink channel and a corresponding downlink

(DL) channel, comprises estimating DL channel matrix; determining receiver processing

matrix; computing effective matrix DL channel H; performing QR decomposition of H;

computing THP matrices; calculating scalar weights for the UEs; processing user symbols

by the THP having the THP matrices to produce an output of filtered vector symbols for

the UEs; directing output of the THP to a channel represented by the DL channel matrix

through which communications occur in the wireless system with the UEs; providing the

receiver processing matrix to the UEs for performing additional receiver processing on

the transmitted signals; and providing the scalar weights to the UEs to be used on the

transmitted signals at the UEs.
