Patent ID: 7526040

Claim:
A receiver comprising: an n plurality of antennas, where n is greater than one; circuitry for obtaining n signals transmitted from m antennas of a transmitter, where m is greater than one; and processing means for developing a sum signal that corresponds to the addition of said n signals that are each pre-multiplied by a respective factor λ j , where j is an index integer specifying that factor λ j multiplies the signal received from antenna j of said n plurality of antennas, developing values for transfer functions α ij , where i is an index that references said transmitting antennas, and j is an index that references said receiving antennas, developing said λ j factors from said transfer functions α ij , and detecting symbols transmitted by said m transmitter antennas embedded in said sum signal, where said λ j factors are components of a vector Λ, where Λ is an eigenvalue of ΛA(Λ*) T , and where A is a matrix containing said elements α ij .
