Cyclic Autocorrelation Based Blind Parameter Estimation of PSK Signals

Parameter estimation of intercepted PSK signals is considered. A new method is proposed for the blind estimation of the carrier frequency and the symbol rate of PSK signals by exploiting a cyclic autocorrelation based statistic within the framework of the cyclostationary theory. This approach does not require multi-dimensional search, is computational efficient, and is easy to implement. Experimental results supporting the method are provided
