This paper presents an efficient channel estimation scheme of the non-orthogonal multiple access system which named CDMA-FMT in 5G wireless networks. The proposed channel estimation scheme is theoretically analyzed based on the equivalent sub-band channel model. Moreover, the simulation results show that, by using the proposed channel estimation scheme, the BLER performance of the CDMA-FMT system outperforms the traditional CDMA system.
