In this paper, we propose an iterative interference alignment scheme to improve the sum rate performance of the K-user MIMO interference channel. We design the precoding matrices to minimize the leakage interference. Linear receiver decoding matrices based on the Minimum Mean Square Error (MMSE) criterion are used to further eliminate the interference. Furthermore, the receiver filter is designed not...
This paper proposes a Dempster-Shafer theory (DST)-based iterative detection-decoding scheme in multiple-input multiple-output (MIMO) systems. On the one hand, the detection algorithm takes advantage of the characteristics of DST processing uncertainty, improving detection performance. On the other hand, during iterations the detection scheme allows for the soft information outputs from the decoder...
