Abstract

Multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) is the key technique for generation communications systems. A new signal detection scheme combining QR and linear ZF detection is proposed for MIMO-OFDM systems. The performance of algorithm is evaluated based on computer simulation. The simulation results indicate that the performance of the propose receiver performs almost as well as the V-BLAST algorithm in MIMO-OFDM systems. However, the complexity of proposed scheme is lower than the standard ZF-VBLAST.
