Patent ID: 8265213

Claim:
A method of supporting transmit diversity based interference cancellation in a receiver, the method comprising: determining a filter as a function of first and second channel models respectively relating the receiver to a first transmitter transmitting a transmit diversity combination signal to the receiver having desired and interfering symbol information, and relating the receiver to a second transmitter transmitting an interfering signal having the interfering symbol information; and detecting desired symbol information by applying the filter to a received signal formed as a first received signal corresponding to a first symbol period or sub-carrier in which the first transmitter transmitted a first transmit diversity combination signal formed from a first desired symbol and a second interfering symbol and the second transmitter transmitted a first interfering symbol, and as a second received signal corresponding to a second symbol period or sub-carrier in which the first transmitter transmitted a second transmit diversity combination signal formed from the first desired symbol and the first interfering symbol and the second transmitter transmitted the second interfering symbol.
