Abstract
The performance comparison of Serially Concatenated Convolutional Codes (SCCC) and Parallel Concatenated Convolutional Codes (PCCC) is evaluated on Additive White Gaussian Noise model channel, which is used as a basis, and actions of SCCC and PCCC on Raleigh faded channels are evaluated in this research work. In DCS the SCCC and PCCC are utilized to reduce the bit error rates. SCCC and PCCC encoder consists of RSCC. The major thrust is iterative decoding. This research has utilized BCJR and TDA decoding algorithms. This research analyzed SCCC and PCCC with interleaved scheme. The BPSK modulation was considered. Performance metric for SCCC and PCCC over Memory less AWGN channel, and memory based channels i.e. Rayleigh slow and fast Faded Channel is BER verses SNR.
