Improved Serially Concatenated Convolution Turbo Code (SCCTC) using chicken swarm optimization

Error-control coding pattern is used in modern communication system to uplift the immunity of noisy communication channel by adding the redundant bits. Suitable tuning of internal parameters of constituent codes leads to considerable enhancement in system performance of Turbo code under AWGN channel condition. In this paper, an optimized Serially Concatenated Convolution Turbo Code (SCCTC) has been suggested to improve BER performance especially at higher values of SNR using Chicken Swarm Optimization (CSO) algorithm. Serially Concatenated Recursive Systematic Convolutional (SCRSC) encoder with different poly2trellis has been used to establish the improvement in BER characteristics mainly in high SNR regions. Moreover, the variation of BER values with the block lengths of the code has also been witnessed. Finally, the BER performance of the proposed SCCTC has been compared with conventional as well as serially concatenated turbo BCH-RSC code.
