Abstract :
In modern communication system error-correction coding pattern boosts sufficient redundancy which in turn upsurges the immunity to pact with the channel impairments. Turbo code can deliver restrained progress in BER performance in an AWGN channel by varying interleaver size and free distance. In this paper, an optimized Parallel Concatenated Convolution Turbo code has been proposed to improve BER performance ominously. The identical Recursive Systematic Convolutional (RSC) encoder has been used to prove the enhancement in BER performance. The simulation result shows that the proposed Harmony-Search (HS) optimized Parallel Concatenated Convolution Turbo code is superior in performance to the conventional Parallel Concatenated Convolution Turbo Code.
