Performance of Turbo Encoder and Turbo Decoder Using MIMO Channel

Sneha Bhanubhai Patel, Mary Grace Shajan

LTE (Long Term Evolution) is the upcoming standards towards 4G, which is designed to increase the capacity and throughput performance when compared to UMTS and WiMax. Turbo codes are a high performance forward error correction at a given code rate. The principle of turbo code permits near approach to Shannon limit, which describes the maximum capacity of the channel. The decoder systems are compared for complexity as well as for equal numbers of iterations. The following figure shows the bit error rate performance of the parallel concatenated coding scheme in an AWGN channel over a range of Eb/No values for two sets of code block lengths and number of decoding iterations. Results show that less complex decoder strategies produce good results for voice quality bit error rates. Simulation of Turbo Encoder and Viterbi Decoder with soft and hard decoding a posterior probability (APP) Decoder has been implemented in Matlab. The result of the Viterbi Decoder using Soft Decision is better than that of the Viterbi Decoder using Hard Decision in terms of the Bit Error rate (BER). Also the simulation of PCC Turbo Coder and APP Decoder was performed and the comparison shows that performance `with MIMO channel is found to be better than without MIMO
