Abstract

This paper presents a kind of improved method of correlation estimation demodulation in order to solve the problem of bit error rate of FM-DCSK in digital communication

through analyzing the relation between modulation information and symbol function of two adjacent bits.Simulation results show that the bit error rate is obviously improved in comparison with the former FM-DCSK system under the condition of the same transmission efficiency.
