The design of no distortion filter based on transient detection

The adjacent-channel interference is one of the main issues about the transient detection in digital communication application which has been a constraint in the future, The sharp cut-off filter and method of the spectrum analysis are often used. However, the baseband information element (te^-at) of the transient detection has much frequency, it is unfavorable for them to be judged by the transient detection at last after spectral analysis or sharp cut-off filter. This paper carries out a method of calculating and compensation to eliminate the adjacent channel interference and weaken the additive noise base on the waveform feature of the transient detection information element. Then the waveform feature of the transient detection information element which has passed channel will be resumed, the final information element will meet the requirements of the transient detection through the procession above.
