Coded Modulation for Communication Systems Employing Robust Reception
Applied Mathematics and Information Science
In what follows the problem of providing reliable communication under intensive interference by means of using robust reception techniques is considered. The aim of this paper is to develop coded modulation schemes for communication systems using various robust reception techniques. The main difference between the solution proposed for the coded modulation scheme employing concatenated coding considered in this work and similar coded modulation schemes that have been considered before is the method of obtaining reliability estimates for the decisions made by the inner code decoder. It has been demonstrated that the proposed solution significantly increases the reliability of the communication link under intensive interference of various types (as compared with the modulation scheme with the same redundancy that does not employ proposed decoding strategy). This has been done by means of simulation of the communication system operation under intensive interference of various types. The results obtained can be used for the development of future generations of communication systems.
