Patent ID: 7218906

Claim:
A wireless system comprising: a plurality of transmit antennas, the plurality of transmit antennas configured to transmit a signal vector; a receiver including a plurality of antennas, the receiver configured to receive the signal vector; and a processor operably coupled to the receiver to receive the signal vector, the processor configured to generate a plurality of symbol decisions ŝ n ; 1≦n≦N from the received signal vector using a first method, where N is a number of sub-channels; subtract a first signal from the received signal vector to form a first modified signal vector, the first signal defined based on a symbol decision generated for a strongest sub-channel of the sub-channels; generate a first improved symbol decision for each sub-channel of the sub-channels except the strongest sub-channel, the first improved symbol decision generated based on the first modified signal vector using a second method; subtract a second signal from the received signal vector to form a second modified signal vector, the second signal based on the generated first improved symbol decision for each sub-channel of the sub-channels except the strongest sub-channel; and generate an improved symbol decision for the strongest sub-channel based on the second modified signal vector.
