Patent ID: 8432980

Claim:
A method of transmitting data with N transmission signals via a multiple-input multiple-output multi-band OFDM transmitter operable to communicate with a receiver adapted to receive data interleaved with a legacy interleaver, the method comprising: parsing data into N parsed data streams; interleaving a first one of the N parsed data streams to produce an interleaved data stream; for i=(1, N−1) producing an i th interleaved data stream by: shifting an i th one of the N parsed data streams by i*x bits where x is the number of bits in a transmitted symbol, and interleaving the shifted i th parsed data stream to produce the i th interleaved data stream; and transmitting each of the N interleaved data streams over sub-bands in a different sub-band order, wherein the transmitting includes hopping over a plurality of sub-bands.
