In this paper, a Differential Chaos Shift Keying system based on Generalized Frequency Division Multiplexing (GFDM-DCSK) is proposed to achieve a system that has higher energy efficiency than DCSK system, solves the delay problem of DCSK system and decreases the decoding complexity of the GFDM system. Neither channel state information nor channel estimation circuits are needed at the receiver side. Numerous simulation results show that the proposed GFDM-DCSK system has better BER performance than DCSK system.
