A Low Complexity VBLAST OFDM Detection Algorithm for Wireless LAN Systems
Wu Yan, Sumei Sun, Zhongding Lei · IEEE Communications Letters · 2004
A low complexity detection algorithm for VBLAST OFDM system is presented. Using the fact that the correlation among neighboring subcarriers is high for wireless LAN channels, this algorithm significantly reduces the complexity of VBLAST OFDM detection. The performance degradation of the proposed algorithm is small compared to conventional detection.
