TOMLINSON HARASHIMA PRECODING WITH ADDITIONAL RECEIVER PROCESSING IN A MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT WIRELESS TRANSMISSION SYSTEM |
摘要 |
<p>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 corresponding downlink (DL) channel, comprises estimating a DL channel matrix Hk; determining receiver processing matrix Vk; computing an 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 the channel represented by the DL channel matrix through which communications occur in the wireless system with the UEs; performing additional receiver processing on the transmitted signals at the UEs based on Vk for each of the K UEs; and using the scalar weights on the transmitted signals at the UEs.</p> |
