Abstract

In this article, design, performance and simulation of wavelet based OFDM V-BLAST MIMO system has been discussed. Wavelet based OFDM technique is based upon orthonormal wavelets bases generated from Haar quadrature mirror filter (QMF) bank. The BER performance of this system has been observed with three different V-BLAST detection algorithms. The three V-BLAST detection algorithms implemented in this article are: zero forcing (ZF), minimum mean squared error (MMSE) and QR-decomposition based V-BLAST detection algorithms.
