Краткое описание

Results of an experimental study of noise immunity of a novel modulation scheme based on bispectrum and triplet signals are presented and discussed. A novel test statistics in the form of peak value of magnitude bispectrum developed for discriminating triplet-signals is developed and studied. Both theoretically derived and experimentally acquired bit error rates are presented and compared for a wide range of bit energy-to-noise spectral density ratio under additive Gaussian noise and multipath fading. A distinctive property of the introduced test statistic is that it is a third-order signal discrimination measure and so enables to extract and indicate such phase dependencies in a priori given in triplet-signals that is not possible for conventional discrimination measure based on second-order statistics, i.e., correlation function and power spectral density estimation. The benefits of the suggested bispectral-based modulation compared to common phase and frequency shift keying are demonstrated and discussed.
