- Abstract
In view of the adverse effects brought by the noise in mine on the ultra-low signal detection, this article puts forward a hardware circuit design of the receiving system and a phase-sensitive detection algorithm which can improve SNR greatly and optimize the system. In addition, an original coding program for synchronization is made to apply to the wireless emergency communications system-PED(Personal Emergency Device)[12]. Through the simulation experiment on PED, it can be concluded that the system is of high detection capability and sensitivity up to 0.75V / nT and 50Hz frequency interference attenuation decreases by -45db. Furthermore, the receiver has strong ability to suppress noise so that faint signal can be detected from where the signal to noise ratio (SNR) is -58db and can decode the information from inoue to mine efficiently
