Patent ID: 7529305

Claim:
A transmitter adapted to process a plurality M of symbol substreams, the transmitter comprising: a space-time coding block adapted to produce M space-time coded symbols per input set of M symbols, each input set of M symbols comprising one symbol per symbol substream, each of the M space-time coded symbols being included in a respective one of M space-time coded streams, wherein each symbol of the M symbol substreams is represented in all M space-time coded streams, wherein the transmitter comprises a delay arrangement, arranged such that for each symbol of the M symbol substreams a time of representation of the symbol in the M space-time coded streams is different for each of the M space-time coded streams, each space-time coded symbol comprising a representation of a symbol of each of the M symbol substreams; a plurality M of transmit antennas each adapted to transmit a respective one of the M space-time coded streams, such that for each symbol of each input set of M symbols, the M space-time coded symbols that contain a representation of the symbol are transmitted at different times.
