چکیده

Abstract:


In this paper, we proposed a novel concatenated coded modulation composed of adaptive turbo code with trellis-coded modulation (ATTCM) that is based on generalized frequency division multiplex (GFDM) system. The proposed scheme has low complexity and provides high spectrum efficiency and significant coding gain. An experiment with 4 Gbit/s novel concatenated coded modulation GFDM system is successfully demonstrated with the proposed method. It is shown that the novel concatenated coding modulation signal (ATTCM 32QAM) provides 2.3 dB coding gain over that of TCM32QAM signal at bit error rate of 1e–3. This paper indicates a prospect solution for the future fifth generation optical access system.

4. Conclusion


In this paper, we have proposed a novel concatenated coded modulation based on GFDM for optical access system. The performance of the scheme combining the adaptive turbo code with trellis coded modulation (ATTCM) was successfully demonstrated in the experiment. The experimental results showed the concatenated coded modulation (ATTCM32QAM) can solve the error floor problem, it provides 7.3 dB(BER = 1e-3) coding gain than uncoded 16QAM signal and achieves 2.3 dB(BER = 1e-3) performance improvement than that of trellis coded modulation 32QAM (TCM32QAM) after 1 km transmission. The results indicates that the designed novel concatenated coded modulation achieved high spectrum efficiency and significant coding gain, the complexity is also reduced by integrating turbo code with trellis code modulation together. This work shows that the proposed method will be a promising solution for future 5G access system.
