Varunkumar B. Mishra, Trushita Chaware, Rajesh S. Bansode . Performance Improvement of Turbo Product Code using Closed Chain Error Pattern Decoding in OFDM system. International Conference and Workshop on Emerging Trends in Technology 2014. ICWET2014, 2 (May 2013), 1-5.
The evaluation of bit error rate (BER) performance for various two dimensional turbo product codes (TPCs) is discussed. The turbo product code decoder is implemented using hard input hard output data, which is impaired by additive white Gaussian noise (AWGN). The effectiveness of the iterative TPC BER is evaluated using non sequential decoding. OFDM is a suitable candidate for high performance of wireless communication systems. OFDM transceiver will be implemented. The use of turbo product coding and power allocation in OFDM is useful to the desired performance at higher data rates. Simulation coding is done over additive white Gaussian noise (AWGN) and impulsive noise (which is produced in broadband transmission) channels. Simulation results demonstrated that, for particular codes, noticeable coding gain improvement of about 2 dB is achieved when compared to the standard sequential HIHO decoding and about 0. 8 dB when compared to the non sequential HIHO decoding. The computational complexity of the CCEP decoder is substantially reduced at moderate and high signal to noise ratios by stopping the iterative process when it is not more beneficial to perform further iterations.
