CP-EBPSK communication system for pseudorandom sequence phase modulation and communication method thereof

The invention discloses a continue phase-extended binary phase shift keying (CP-EBPSK) communication system for pseudorandom sequence phase modulation and a communication method thereof. On the basis of a CP-EBPSK modulation mode, the CP-EBPSK communication system comprises a CP-EBPSK modulator of pseudorandom sequence phase modulation and a CP-EBPSK demodulator of pseudorandom sequence phase modulation. According to the CP-EBPSK modulator of pseudorandom sequence phase modulation, a pseudorandom sequence generator is added to an original CP-EBPSK modulator and the pseudo random number generated by the pseudorandom sequence generator is utilized to randomly select a symbol of the delta. And the CP-EBPSK demodulator of pseudorandom sequence phase modulation includes an impulse filter that is used for highlighting phase modulation information of a received signal and eliminating the polarity changes, so that the demodulation performance is not influenced by pseudorandom sequence modulation. According to the inv
