Abstract

Abstract: To overcome the intra-signal interference components and the large average bit energy existing in decision variables, an improved RM-DCSK algorithm, named ORM-DCSK, is proposed. An orthogonal chaotic generator is designed to eliminate the intra-signal interference components. Besides, the signal frame format is expanded to reduce the average bit energy. The BER is derived and simulated in AWGN channel. The simulation results show that ORM-DCSK performs greatly better in BER performance than RM-DCSK algorithm without sacrificing transmission rate.
