Abstract:
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; andprocessing means fordeveloping a sum signal that corresponds to the addition of said n signals that are each pre-multiplied by a respective factor .lambda..sub.j, where j is an index integer specifying that factor .lambda..sub.j multiplies the signal received from antenna j of said n plurality of antennas,developing values for transfer functions .alpha..sub.ij, where i is an index that references said transmitting antennas, and j is an index that references said receiving antennas,developing said factors .lambda..sub.j from said transfer functions, where said factors are components of a vector .LAMBDA. where .LAMBDA. is an eigenvector of A, and where A is a matrix containing said elements .alpha..sub.ij, anddetecting symbols transmitted by said m transmitter antennas embedded in said sum signal.
