Abstract
In this paper a VBLAST-OFDM system with linear constellation precoding (LCP) is proposed for wideband wireless communications. Frequency diversity is obtained through the LCP precoding across OFDM subcarriers. Also a joint VBLASTLCP decoder which combines classical V-BLAST successive interference cancellation with Maximum Likelihood decoding for the precoding is proposed. Computer simulation shows that VBLAST-OFDM-LCP has a performance gain of at least 8.5dB at a certain symbol error rate compared with VBLAST-OFDM.
