Patent ID: 7613259

Claim:
An apparatus, comprising: a correction circuit coupled to receive a first symbol transmitted from a first antenna at a one time and a complement of a conjugate of a second symbol transmitted from a second antenna at the one time, and coupled to receive the second symbol transmitted from the first antenna at another time and a conjugate of the first symbol transmitted from the second antenna at the another time, and coupled to receive a first fading parameter estimate signal determined from a first plurality of symbols transmitted from the first antenna, the first plurality including the first symbol and the second symbol, and coupled to receive a second fading parameter estimate signal determined from a second plurality of symbols transmitted from the second antenna, the second plurality including the complement of the conjugate of the second symbol and the conjugate of the first symbol, the correction circuit producing a first symbol estimate in response to the first symbol and the conjugate of the first symbol and the first and second fading parameter estimate signals and producing a second symbol estimate in response to the second symbol and the complement of the conjugate of the second symbol and the first and second fading parameter estimate signals; and a combining circuit coupled to receive a plurality of symbol estimates including the first and second symbol estimates, the plurality of symbol estimates corresponding to a respective plurality of signal paths, the combining circuit producing a first symbol signal in response to the plurality of symbol estimates.
