Detection of SS signal cyclic spectrum based on AO technique

  • The spread spectrum (SS) signal modulated by pseudo noise code is typically cyclostationary (CS) signal. Based on the spectral correlation theory of CS signal, a cyclic spectrum detection method of SS signal using acousto-optic (AO) signal processing technique was presented. The cycle frequency and cyclic spectrum of the SS signal as well as AO CS processing model were investigated. Via AO CS time-integrated correlator, the AO correlation function (cyclic spectrum) of SS signal was detected at the cycle frequency. Compared with the conventional signal energy detection methods, the cyclic spectrum detection has better detection characteristic. For noise and interference, no matter what they are stationary or non-stationary, the cyclic spectrum detection is with the quite anti-interference capability. The simulation results show the effectiveness of the method.
