Abstract
The majority of the signals accepted by radio reception arrangements, has complex time-and-frequency parameters and concern to non-stationary. For the analysis of such signals the method is needed, allowing to receive good permit both on frequency, and on time.
The article discusses an assessment of a interchangeable degree of wavelet connection and a signal with a view of increase of efficiency of the wavelet-analysis is.
There is a methodology of a choice of wavelet for the analysis of time-and-frequency characteristics of a non-stationary signal.
As for the examples of the analysis of the actual signal recorded from an ether efficiency of the offered approach in the analysis of complex non-stationary signals on the basis of direct continuous wavelet -transformation is confirmed.
