Abstract:
An improved interleaver design to fully explore the diversity of the MIMO OFDM systems provides higher diversity gain than usual. A method for wireless data communication using such interleaver design implements parsing a bit stream into multiple spatial data streams, interleaving the bits in each spatial data stream by performing bit circulation and column swapping to increase diversity of the wireless system, and transmitting the bits of each spatial data stream.
