“…The other method for VSK signal processing with a better quality is the simulation of the likelihood ratio. In contrast to the optimal receivers based on the average risk minimum criterion we developed in [7] and [8] for the determinateform signals, a priori data, in this case, are the modulating noise variance and the single pulse duration, but not parameters of pulses amplitude and their carrier frequency.…”

This paper investigates the possibility of real-life using the brand new type of digital modulation, which implies the transmission of white Gaussian noise whose variance changes in time. That modulation has been entitled as variance shift keying. The signals obtained on its basis have a high level of transmission security, and they even cannot be detected by standard means of matched filtering. However, the paper suggests the decision on how to process these signals at the receiver site. It is proposed to use a specially developed optimal receiver, whose restoration quality appears to be better in comparison with the conventional cumulative receiver. The digital simulation of propagation in frequency selective media has shown the signal with variance shift keying is possible to be used in real conditions since its distribution of instantaneous amplitudes remains Gaussian.
