T1 MULTI FREQUENCY SYNTHEZIER OF BISPECTRAL TRIPLET- SIGNAL DESIGNED FOR DIGITAL COMMUNICATION SYSTEM JF Telecommunications and Radio Engineering JO TRE YR 2017 FD 2017-05-19 VO 76 IS 2 SP 147 OP 155 K1 digital communication system K1 Gaussian noise K1 interference immunity K1 double-frequency quartz generator K1 bispectrum K1 triplet-signal K1 bit error rate K1 signal-to-noise ratio AB 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 triplet-signals 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.
