Paper is dedicated to novel bispectrum-based signal processing technique using triple-channel heterodyning procedure performed for triplet-signals in digital communication systems. Test statistics exploited for detection and discrimination of triplet-signals are evaluated in the form of the bimagnitude peak values according to the maximum likelihood rule. Novel strategy developed for fast bispectrum-based signal processing is suggested. Experimental study of noise immunity in bispectrum-based digital communication system is carried out for suggested triple-channel heterodyning technique. Bit error rate (BER) values are computed under influence of additive Gaussian noise in radio communication link for wide range of variations of input signal-to-noise ratio (SNR).
