Patent ID: 7643404

Claim:
A method for communicating data from a transmitting section of a first device having M 1 transmitting antennas to a receiving section of a second device having M r receiving antennas, comprising: at said transmitting section of said first device: transforming a first data block into M 1 /2 signals by a first space-time encoder; and a second data block into M 1 /2 signals by a second space- time encoder, thus creating M 1 signals forming an OFDM block from each of said M 1 , signals, thus forming M 1 OFDM blocks, and transmitting each said M 1 OFDM blocks over a respective one of said M 1 antennas; and at said receiving section of said second device: simultaneously receiving the transmitted signals said M 1 receiving antennas to form received signals; employing maximum likelihood decoding to decode said first and second data blocks contained in said received signals; if the first decoded data block is determined to be in error and the second data block is determined to be error free, or if the second decoded data block is determined to be in error and the first decoded data block is determined to be error free, re-encoding the error free decoded data block; regenerating the re-encoded data block and removing the regenerated data block from the received signals, thereby forming modified received signals; and re-decoding the modified received signals.
