Patent ID: 7555078

Claim:
A reception method, in a multiple-input-multiple-output transmission system comprising a transmitting station which transmits a first data stream and a second data stream using separate transmitting antennas and a receiving station which separates and outputs said data streams from signals received by first and second receiving antennas, the method comprising the steps of: computing a bit estimate value of the first data stream from signals received by the first and second antennas; computing a bit estimate value of the second data stream from signals received by the first and second antennas; refining the bit estimate value of the first data stream using the bit estimate value of the second data stream; refining the bit estimate value of the second data stream using the bit estimate value of the first data stream; repeatedly refining the bit estimate value of the first data stream using the bit estimate value of the second data stream, and repeatedly refining the bit estimate value of the second data stream using the bit estimate value of the first data stream; and after a prescribed number of repetitions, deciding bit for the first data stream based on said bit estimate value for the first data stream, and deciding bit for the second data stream based on said bit estimate value for the second data stream.
