Abstract

Identification of the modulation type of a received signal is a problem encountered in radio spectrum surveillance and control. It is attractive to design methods that use only one or two time-domain classification parameters, in order to minimize the computational complexity. A number of new classification parameters are proposed and studied in this paper. They are compared to an existing one-parameter method. Also, a new method of envelope extraction, which does not require Hilbert transform computation, is proposed. The proposed methods achieve better recognition rates at short data records, e.g. 89% vs. 82% at 10 dB, 1024 samples, and 95% for a combination of two parameters
