Tiivistelmä

A technique for improving the noise immunity of digital communication systems by the exploiting novel bispectrum-organized modulation and demodulation procedures and by using the novel test signal detection and discrimination statistic in the form of bispectrum magnitude peak is suggested. Practical schema designed for synthesis of bispectral-organized tripletsignals for digital communication systems is suggested and studied. Communication channel model with additive Gaussian noise is considered in computer simulations. The results of computations of bit error rate carried out within wide limits of bit energy to the spectral density of the additive Gaussian noise ratios demonstrate the benefits provided by the suggested technique as compared to the well-known frequency shift keying modulation using common energy-based signal detection test statistics that evaluated in the form of the correlation integral maximum estimate.
