AbstractA pseudo-noise code-tracking spread spectrum receiver able to quickly acquire and track incoming signals includes an adaptive weighting system for the outputs of parallel-fed correlator channels in which the weighting system automatically detects the degree of correlation in each channel, sets the detector characteristic to increase the weight for a correlator channel exhibiting a high degree of correlation, and decreases to zero the weights on all others.
