Abstract :
In this paper a differential-coding method is applied to improved FM-DCSK transmitter to simplify the receiver configuration. Further based on our proposed scheme, a new error correction principle is presented to enhance the noise performance of the purposed system. The BER performance of the different FM-DCSK systems including proposed one is investigated over AWGN channels. Simulation results show that the proposed system using new error correction algorithm owns a comparable noise performance and much lower complexity and delay comparing improved systems.
