The method can automatically recognize the classical band-pass single carrier modulations such as ASK (Amplitude Shift Keying), PSK (Phase Shift Keying), FSK (Frequency Shift Keying), QAM (Quadrature Amplitude Modulation), and the multicarrier OFDM (Orthogonal Frequency Division Multiplexing), such as the DMT (Discrete Multi Tone) required by the ADSL (Asymmetric Digital Subscriber Line) and VDSL (Very high-speed Digital Subscriber Line) standards, and by the Home Plug 1.0 PLC (Power Line Carrier) transmission.This paper presents the first experimental results obtained by applying the proposed method on simulated signals in different environments in order to evaluate its performances and application range.A classification algorithm using higher order statistical analysis via fourth order cumulants is proposed. Modulation classification results are presented testing signals with different SNR and modifying the amount of averaged cumulants for obtaining a classification result.

We also highlight the advantages and disadvantages of each technique in classifying a certain modulation scheme. Prerequisites: EGRE 207 and MATH 301, both with a minimum grade of C. Problem-solving, top-down design of algorithms, basic C syntax, control structures, functions, arrays, files and strings. PDF format Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier.The objective of this work is to assist newcomers to the field to choose suitable algorithms for intended applications. The laboratory introduces fundamental testing, measurement, troubleshooting methodology and proper laboratory notebook maintenance.
