Patent ID: 8654892

Claim:
A wireless device comprising: a wireless interface; and processing circuitry, the wireless interface and the processing circuitry operable to process bits of an input symbol to form N orthogonal frequency division multiplex (OFDM) transmit streams across K subcarriers, wherein at least one input symbol comprises KN subsymbols, wherein at least one of the KN subsymbols comprises B bits of the input symbol and wherein each subsymbol is communicated via an associated subcarrier of the N transmit streams by: interleaving the bits of the input symbol by at least one permutation to form permutated bits; grouping permutated bits into subsymbols; grouping the subsymbols into blocks of subsymbols; and rotating the blocks of subsymbols between the N OFDM transmit streams, wherein N is greater than 1.
