Abstract

Soft input soft output (SISO) decoder is an essential part of linear turbo equalizer. Soft-Input Soft-Output (SISO) decoder can be designed to accomplish various algorithms. In this presented paper, we analyze the different iterative algorithms utilized for implementation of the SISO decoder architecture also, a comparative analysis of iterative algorithms are contemplated. Simulation results shows that proposed realization gives improved bit error rate (BER) performance with optimal signal to noise (SNR) ratio.
