The assertion on the method of formation of a system of basic functions of the communication channel input and output (carriers) is established. The solution of the problem by a numerical method is obtained. The assertion on its accuracy based only on the original data is established. An algorithm for the shaping of basic function is developed. © 2010 by Begell House, Inc. Source

The opportunity for correction of a continuous communication channel with constant parameters by the criterion of the maximum capacity is discussed. It is pointed that potential characteristics of the continuous communication channel should be taken into account, even when digital information transmission systems are synthesized. The problem of computation of the channel capacity with a random power transmission factor is stated and solved. The discrepancy between the existing criteria of the synthesis of linear systems and the problems solved by the systems of information transmission is demonstrated. A problem of synthesis of a linear system to increase the potential characteristics of the communication channel is stated. © 2010 Begell House, Inc. Source

The article presents a mathematical model of the adaptive system for coding (ASC) a wideband speech signal (WSS), using a psychoacoustic model (PAM). The developed mathematical model demonstrates the capacity for information resource distribution in a codeñ with a variable structure. © 2013 by Begell House, Inc. Source
