To meet the development of 5G networks, a novel coding and modulation method based on generalized frequency division multiplexing(GFDM) and adaptive Turbo code and trellis coded modulation cascade is proposed in this paper. The principle of new cascaded coding modulation is described, and the simulational and experimental platform of generalized frequency division multiplexing based on cascaded coding modulation are setup. The results show that compared with uncoded 16 QAM, the performance of the new cascaded coded modulation is significantly improved. This method achieves high spectral efficiency and high coding gain performance, which provides a flexible solution for the development of 5G technology.
