OPTIMAL RECEIPTION OF BISPECTRAL-ORGANIZED BINARY SIGNALS-TRIPLETS IN CHANNEL WITH FADING

V.V. Naumenko, A.V. Totsky

A noise-resistant technique based on bispectral-organized modulation and demodulation by using test statistic for signals-triplets detection and discrimination computed in the form of peak value of magnitude bispectrum estimate is proposed. Computation results related to the bit error rate depending upon bit energy to noise spectral density ratio are represented for additive Gaussian noise channel with fading and without fading. The gain and benefit in noise resistance provided by suggested technique comparing to common frequency keying FSK and FSK-4 techniques using test statistic in the form of maximum of correlation integral are demonstrated.

Key words: noise resistance, bispectrum, triplet, fading
