Noise immunity of information transmission system with pseudorandom frequency switching under worstcase interference conditions
Abstract
A method is proposed for analyzing the noise immunity of data transmission systems employing pseudorandom frequency switching for worstcase distribution of intereference by frequencies. The problem is formulated as a minimax game problem of synthesizing counteracting dynamic systems. The effectiveness of the transmission system is defined by its noise immunity, represented by the average error probability. The optimum interference strategy is assigned by finding the distribution function of the interference by frequencies. The noise immunity of a pseudorandom frequencyswitching transmission system in which information is transmitted at each frequency by phaseshift keyed pseudorandom (wideband) signals, employing coherent processing in the receiver, is estimated as an example.
