THE TECHNIQUE OF DIRECT CALCULATION OF NOISE IMMUNITY OF THE MULTIPOSITION-KEYED RADIO SIGNAL OPTIMAL COHERENT RECEPTION

摘要

Usually, in the tutorials and monographers devoted to an optimum reception of the discrete messages, the rules for a general case of multiposition-keyed radio signal are discussed. At the same time, the derivation of the formulae for calculation of a potential noise immunity is performed only for signals with two positions. Although the calculation according to the formulae (2) and (8) is considered to be a straight methodic, the solution to these integrals in the accessible literature is not present. This is especially true for the reception of non-orthogonal signals. The presented material below fills the indicated gap in the theory of potential noise immunity.
