Combiner for two dimensional adaptive interference suppression system

A multisignal enhancement combiner system comprising:

• a radio receiver for converting received signals into in-phase and quadrature samples of the received signals;
• a signal processor for receiving the in-phase and quadrature samples from the radio receiver, the signal processor producing an amplitude transform signal A and a phase difference transform signal P and producing intermediate signals of the received signals including a variance of amplitude signal .omega..sup.2 and a variance of phase difference signal v.sup.2 ;
• a first weighting signal generator receiving the variance of amplitude signal .omega..sup.2 for producing a weighting signal N.sub.1 which is inversely proportional to the variance of amplitude signal .omega..sup.2 ;
• a second weighting signal generator receiving the variance of phase difference signal v.sup.2 for producing a weighting signal N.sub.2 which is inversely proportional to the variance of phase difference signal v.sup.2 ;
• a first multiplier for multiplying the weighting signal N.sub.1 times the amplitude transform signal A to produce a weighted transform signal N.sub.1 A;
• a second multiplier for multiplying the weighting signal N.sub.2 times the phase difference transform signal P to produce a weighted phase difference transform signal N.sub.2 P;
• a summer for summing the weighted signals N.sub.1 A and N.sub.2 P to produce a final output transform signal K whose best performing signal component is enhanced, the final output transform signal K being inserted into a radio demodulator to output interference suppressed signals.
