The comparison between Asymmetric Turbo Code using O´ QPP Interleaver and LTE Turbo Code

This paper aims to compare the performance of Asymmetric Turbo Code and the LTE Turbo Code. The LTE Turbo Code refers to a symmetric turbo code utilizing the component codes [1 15/13] on both RSC encoders and QPP Interleaver. The component codes of asymmetric turbo code are specifically developed for the LTE frame length of 128, 256 and 752, while they are utilizing the ΩQPP Interleaver. The simulation shows that the Asymmetric Turbo Code may outperforms the LTE turbo code on the LTE frame length of 256 and 752, giving the coding gain difference 0.1 dB at BER 10-6. However, on the frame length of 128, the LTE turbo code is better than the asymmetric turbo code, giving the coding gain difference 0.3 dB.
