摘要：
The paper expounds a new method for detecting signal from strong noise-transient detecting method. The received signal which passed the channel is always written as E(t)= s(t)+n(t). Because the binary signal's carrier waveform in digital communication can be known at first, its character of waveform that designed in sending end must have difference from the noise. First, s(t) can be deleted from E(t) through the special differential equation in receiving end, then the differential coefficient equation only about received signal E(t) and noise N(t) can be found, solving the equation and getting N(t), final, the detected signals S(t) can be got from S(t)=E(t)-N(t).
