Abstract
Multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) is the key technique for generation communications systems. In this paper an enhanced signal detection scheme is proposed for MIMO-OFDM systems. A combining QR and PIC MIMO detection scheme was directly applied to MIMO-OFDM systems. The performance of algorithm is evaluated based on computer simulation. The simulation results indicate that the performance of the propose wideband receiver outperforms the V-BLAST in MIMO-OFDM systems. At symbol error rate 1e-3, the proposed scheme can obtain the 2dB gain to V-BLAST algorithms based on MIMO-OFDM systems.
