A new method of detecting the weak known Signals base on transient character

摘要：

The paper expounds a new method for detecting signal from strong noise--transient detecting method.The received signal is always written as E(t)=s(t)+n(t). Because the binary signals carrier waveform in digital communication can be known at first, its character of waveform must have difference from the noise.First, s (t) can be deleted from E(t) through the special differential eaqution, then giving out the differential coefficient equation only about received signal E(t) and noise N(t), solving the equation and getting N(t),final, the detected signals S(t) can be got from S(t)=E(t)-N(t).
