Abstract: In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.
