Extraction of Polyphase Modulation Parameters Using Cyclic Spectral Analysis
Xin Zhang, Feng Liu, Peng Zheng, Hui Fa Xu · Applied Mechanics and Materials · 2012
This paper presents an efficient algorithm to extract the polyphase modulation parameters from intercepted signals. The algorithm is essentially based on the cyclic spectral analysis method. A calculation of parameters extraction relative error as a function of different signal patterns reveals the performance of the algorithm, which is validated via simulation examples.
