Noise Stability of a Class of Wideband Systems for the Transmission of Discrete Information with Signal Fading

This paper considers the noise stability of wideband systems for the transmission of discrete information with separate processing of the orthogonal components of the received signal in a channel with fading and additive fluctuation noise. Expressions are obtained for the error probability and a comparative analysis is performed of the noise stability of different variants of realization of these systems depending on the degree of correlation of the fading of the signal components.
