A novel THP and detection joint equalization algorithm for MIMO frequency selective fading channels.

Abstract: This paper gives a novel temporal Tomlinson-Harashima Precoding (THP) and spatial detection joint processing algorithm for Multiple-Input Multiple-Output (MIMO) frequency selective fading channels. Generally spatial and temporal signals are processed at transmitter side, or at receiver side, both are very complex indeed. In this paper, we propose a novel temporal THP (T-THP) and spatial decision feedback equalization (S-DFE) detection joint processing technique, at transmitter, T-THP to each sub-channel of MIMO channel model is performed, through this step, the channel model is changed into flat fading MIMO channel; Then at receiver side, adopt MIMO detection to cancel interference from different antenna or multi-user, and at last, the estimated signal will be got. Using this solution, we can change the space and time 2-dimension''s operation into two 1-dimension''s operation separately, and in each space, the algorithm is relative simple. From algorithm analysis and performance comparison, we can see the validation and advantage of this method suggested in this paper [Copyright &y& Elsevier]
