| Abstract: | Strip Spectral Correlation Algorithm(SSCA) is a kind of computationally efficient algorithm for cyclic spectrum.It is important for detecting and estimating parameters of cyclic stationary signals.We can detect and estimate parameters by making use of cyclic features in low SNR environment.This paper studies the implementation of SSCA on TS201S and analyses the cause of the parameters being selected in real-time operation.The key point of the project and the resolvent are also discussed.Last,the way of opti... |
