Аннотация

The study of restored speech quality at the output of noise-immune and protected voice transmission systems based on V.A. Kotelnikov theorem and Khurgin-Yakovlev representation under the influence of various interferences in a commu-nication channel is given. The task of the study is to determine the best combina-tions of encryption algorithms and primary coding to achieve the highest quality of restored speech information at the output of primary decoder under the influence of interference in a communication channel, as well as to study the application of V.A. Kotelnikov theorem and Khurgin -Yakovlev representation when building primary codecs. The aim of the work is to choose and prove the algorithms for primary coding and encryption of noise-resistant and secure system for transmit-ting voice signals which provides the highest value of voice quality assessment at the output of transmission system in a given range of transmission rates and inter-ference in a communication channel. The result of the research is to select best combinations of algorithms for primary coding and encryption, as well as to use Khurgin -Yakovlev representation in order to improve the quality of restored speech, noise immunity and security of transmitted information at the output of voice transmission system.
