A New Method of Receiving BPSK Signal

摘要

The coherent detection of BPSK signal was studied in this paper. The new method of receiving BPSK signal was developed on the base of the traditional coherent detection. This new method produces a smaller average probability of bit error(P_e) than traditional detection for a given value of the transmitted energy per bit. For the smae average probability of bit error this method requires the signal-to-noise ratio that is 3dB less than traditioal coherent detection. This paper provides references and suggestions for further study in coherent detection technique of digital communication. It is also useful to reform equipment of digital technique of digital communication. It is also useful to reform equipment of digital communication system.
