Patent ID: 7046737

Claim:
A method of detecting symbols transmitted wirelessly from n number of transmitting antennas, the method comprising: receiving transmitted signals from the n number of transmitting antennas by an m number of receiving antennas; determining transfer functions α ij for each wireless data channel by processing the received signals, wherein each wireless data channel is a path from one transmitting antenna to one receiving antenna; forming an n×m matrix A, wherein the channel transfer functions α ij represent elements of the matrix A; finding an eigenvector Λ associated with a maximum eigenvalue of matrix A, wherein λ j represent m elements of the eigenvector Λ; computing S, wherein S is an inner product of the eigenvector Λ and a vector whose element ξ j is the signal received by the j th receiving antenna; computing γ i 's, wherein γ i is an inner product of a i th row of the A matrix and the eigenvector Λ; and detecting the transmitted symbols, utilizing γ i 's and S under a maximum likelihood detection scheme.
