ABSTRAKT

A classification scheme of radio signals and basic methods for their modulation (manipulation) are developed. The expediency of using simulation modeling by means of MATLAB + Simulink for investigations of radio equipment (RE) for detection of radio signals with different structures and the a priori known radio signal parameters is substantiated.
Simulation models of a correlation receiver, a quasioptimal filter receiver with an envelope detector, and a quadratic detector and integrator [energy detector (ED)], a receiver with frequencymodulated signals, a receiver with PTWF, and the results of investigations using these models are presented.
