Performance Evaluation of Turbo Code System under Jamming Environment

Abstract

This paper evaluates the effect of Frame- size, Code rate and Decoding iteration as efficient parameters on turbo code system performance. For this study, first a turbo code system was simulated by MATLAB software to study the effect of mentioned factors in different ranges of value on performance of turbo code system and then the performance of turbo code under the effect of jamming signal was evaluated to investigate the effect of jamming signal on bit error rate (BER) performance. The results show increasing the Frame- size, Code rate and decoding iteration, better BER performance of turbo code system is achieved and also it is deduced from the results that turbo code system can act as good anti-jamming code with acceptable code rate.
