Blind detection and parameter estimation of MSK signal based on cyclic spectrum
Ran Tao · Information and Electronic Engineering · 2012
According to the cyclostationarity of Minimum Shift Keying(MSK) signal,the properties of the cyclic spectrum for the signal is analyzed,and a signal detecting method exploiting cyclostationary in frequency domain is proposed by applying the asymptotically optical chi-squared test.Then a parameter estimation method for carrier frequency and chip width is proposed,which avoids multi-dimensional search.The simulation results have proved the validity of the method in low signal to noise ratio.
