This paper considers the implementation of Tomlinson-Harashima (TH) precoding for multiuser MIMO systems based on quantized channel state information (CSI) at the transmitter side. Compared with the results in , our scheme applies to more general system setting where the number of users in the system can be less than or equal to the number of transmit antennas. We also study the achievable average...
This paper considers the implementation of Tomlinson-Harashima (TH) precoding for multiuser MIMO systems based on quantized channel state information (CSI) at the transmitter side. We study the sum rate of a greedy user scheduling algorithm combined with the quantized CSI-based TH precoding, termed G-THP-Q. The asymptotic distribution of the output signal to interference plus noise ratio of each selected...
