TOMLINSON HARASHIMA PRECODING WITH ADDITIONAL RECEIVER PROCESSING IN A MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT WIRELESS TRANSMISSION SYSTEM |
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 Heff; performing QR decomposition of Heff; 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.
