Phased-locked signal detection system based on parallel optimal receivers by average risk criterion

[摘要] This paper is devoted to the investigation of a developed sync system which is based on optimal receiver by average risk minimum criterion when detecting the reflected radar impulse under conditions of Gaussian and Johnson noises. M-sequence with single pulse phase-shift keying has been chosen as a reference signal. A transceiver has been implemented during the digital experiment. The use of developed self-Tuning system allows applying the optimal methods of reflected radar signal detection when it is noncoherently received under conditions of Gaussian and non-Gaussian noises. It has been proved that the developed sync system has the signal detection quality advantage over the system based on matched filter.
