Abstract

A new minimum-total-mean-square-error (MTMSE) criterion based vector perturbation precoder is proposed for multi-user multi-stream MIMO downlink, which has much lower computational complexity and slightly better BER performance than the traditional MTMSE-MUMS-VP precoder we proposed before. Furthermore, the proposed precoder is verified on a Xilinx Virtex-4 FPGA at 400MHz. Many slices resource can be saved due to the reduction of complexity, and with 16QAM constellation the data throughput is up to 12.8Gbit/s in a {2,2,2,2} × 8 MIMO configuration.
