signals received by receiver 32 are determined by a complex channel transfer function matrix h having elements h 11 h 12 etc in other words the transmitted signal vector s made up of the individual complex signals s 1 and s 2 transmitted by antennas 24 and 26 and the received signal vector x made up of x 1 and x 2 are related by the expression here n represents the noise received at each antenna h ij is the complex transfer function from transmit antenna i to receive antenna j and represents generally a frequency selective dispersive channel between these particular transmit and receive antennas the off diagonal terms in h represent the interference between the transmission channels receiver 32 adaptively cancels this interference as described in detail hereinbelow fig2 is a block diagram showing elements of receiver 32 in accordance with an embodiment of the present invention the signals received by antenna 28 is separated into orthogonal polarization components by an orthogonal mode transducer omt 38 the two orthogonal components are input to respective rf receiver circuits 40 and 41 which performs analog processing and downconvert the signal under control of respective local oscillators 42 and 43 the use of separate local oscillators.
