Patent ID: 7899125

Claim:
A transmitter comprising: an input bit multiplexer to route bits of an input data signal to be divided among a plurality of stream groups; wherein each stream group of said plurality of stream groups is processed by a plurality of baseband signal processors in parallel to generate a set of orthogonal frequency division multiplexed (OFDM) stream-symbols; a plurality of intra band group time frequency coding units, wherein each of the plurality of intra band group time frequency coding units is operably coupled to outputs of the plurality of baseband signal processors of each stream group, wherein said intra band group time frequency coding unit is able to interleave the set of OFDM stream-symbols from said baseband signal processors of each stream group and to output an interleaved signal; an inter band group time frequency coding unit operably coupled to the plurality of stream groups to interleave interleaved signals outputted by the plurality of intra band group time frequency coding units; an inverse fast Fourier transform unit to perform an inverse fast Fourier transform operation on a combined signal formed from an interleaved signal from all stream groups, said interleaved signal from each stream group from a set of OFDM stream-symbols from all streams in each respective stream group.
