Patent ID: 7899128

Claim:
A transmitter configured for transmitting a single input data stream over two or more spatial channels using orthogonal frequency division multiplexed (OFDM) signals, the transmitter comprising: a commutator to select bits from the single input data stream for two or more bit streams; two or more encoders, each to encode bits of one of the bit streams, wherein the commutator operates at a bit rate and sequentially provide the selected bits of the input data stream to the encoders; a block permuter associated with each spatial stream; and a spatial bit sequencer having a plurality of inputs and a plurality of outputs, each input coupled to an output of one of the encoders and each output coupled to an input of one of the block permuters, the spatial bit sequencer to select groups of encoded bits from each of the encoders and to assign individual bits of a selected group at the bit-rate to each of the block permuters in a sequential manner to distribute bits from the selected group across the block permuters, the block permuters to perform a block interleaving operation on blocks of bits of an associated spatial stream to produce interleaved blocks of bits for the associated spatial streams.
