PERFORMANCE COMPARISON OF PROPOSED INTERLEAVER WITH DIFFERENT TYPES FOR PARALLEL TURBO CODE

Abstract

Interleaver type is important in parallel turbo code system. It’s responsible of improve code performance against additive white Gaussian noise AWGN. In this paper, introduce a new interleaver with its mathematical model. Study its performance as comparison with different interleavers, including random interleaver, QPP quadratic primitive polynomial interleaver as standard of LTE, chaotic interleaver and finally 2-D interleaver for burst error environment, Study the performance as simulation. The system takes in consideration also different modulation schemes including QPSK, 16-QAM and 64-QAM. Result comparison between different types summarized in performance BER curves and tables.
