An efficient high performance turbo code implementation in Rayleigh fading channel

摘要

Turbo codec in 3GPP LTE standard is implemented in an existing Rayleigh fading channel. Its bit error rate (BER) performance is gauged. The research is investigated to compare the performance of turbo codes with traditional Quadratic Permutation Polynomial (QPP) interleaver and comparatively simpler matrix interleaver in Rayleigh flat fading channel. The simulation outcome reveals that the BER performance of turbo codec with matrix interleaver outruns the performance with QPP interleaver.
