Industrial Automatic Control Systems and Controllers Annotation << Back A Method for Suppressing Adjacent Channels in a Superheterodyne Radio Receiver with Digital Signal Processing A.N. Rudnev A method for suppressing adjacent channels (SC) in a superheterodyne radio receiver (RR) with digital signal processing (DSP) based on the principle of frequency-dependent phase compensation (CHZFC) is proposed. The principle of CHZFC is stated, which allows to increase the degree of SC suppression and reduce the requirements for a digital filter of concentrated selection (FSS). A block diagram of a radio receiver is presented. The results of software modeling are presented. The energy indicators of SC suppression are presented. Keywords: superheterodyne; adjacent channel; digital signal processing; FSS; frequency-dependent phase compensation. DOI: 10.25791/asu.11.2022.1399 Pp. 38-43.
