| Abstract: | To reduce distortion due to AWGN(Additive White Gaussian Noise) in transmission channel of DCSK(Differential Chaos Shift Keying) chaotic communication system,an improved system scheme was proposed Which is called PI-DCSK(Phase Inversion Differential Chaos Shift Keying) chaotic communication system based on DCSK modulation system.According to the delay retransmission mechanism of information signal and reference signal had a half-symbol period delay at the transmitter in the DCSK system;then at the PI-DCSK r... |
