Integrated design of digital communication systems for fixed channel conditions

Abstract

This paper presents a new algorithm for the integrated design of digital communication systems. In order to design the system as a whole, all the restrictions and key subsystems of a communication system are taken into consideration. The algorithm produces appropriate design parameter values for the source coding, channel coding and modulation functions. Several design examples are provided to illustrate the utility of the approach. This algorithm is quite general and not application-oriented, as was the case in prior work in joint source-channel coding. A large variety of existing methods for source coding, channel coding and modulation may be utilized in achieving a practical system design.
