Patent ID: 8311162

Claim:
A method for suppressing interference associated with receiving data, via a wireless channel at a receiving unit, from multiple antennas of a transmitter of interest, the method comprising: receiving an information carrying signal transmitted in a multi-antenna transmission from the multiple antennas of the transmitter of interest, said multi-antenna transmission corresponding to two vectors of symbols; generating first and second vectors, each associated with a corresponding one of the two vectors of symbols; forming a covariance matrix (R) based on the generated first and second vectors, which covariance matrix (R) has four block elements, the four block elements including first, second, third, and fourth matrices, the third matrix being a complex conjugate of the second matrix with opposite sign and the fourth matrix being a complex conjugate of the first matrix; and jointly decoding the first and second vectors based on an inverse of the formed covariance matrix (R −1 ), to estimate the symbols transmitted in said multi-antenna transmission and to suppress said interference.
