Abstract :
This paper mainly studies combining the nonuniform M-QAM schemes with interleaving applied to wireless multimedia transmission for MIMO-OFDM systems. The four models we have considered are Zero-forcing, QR-blast, V-blast, and Maximum likelihood search. We have performed the simulation of a stream H.264 example with non-uniform, interleaved 16-QAM. From the simulation results, we present the significant improvement in terms of the bit error rate performance, for these four MIMO models.
