Abstract

Efficiency of protection constructions is usually estimated by criterion of “signal-to-noise ratio” at the reception point. In this paper it is proposed to use criterion of speech intelligibility, which is more suitable from viewpoint of finite user. Represented results of computer simulation show constructiveness of proposed approach.
