Synthesis of a device for anti-jamming reception of signals of tonal rail circuits on the background of additive five-component interference

An optimal receiving device for information signals of tonal rail circuits has been synthesized. The are observed against the background an additive five-component interference. first component interference is broadband Gaussian noise. other four components structurally determined: single impulse interference, from adjacent circuit, and multiharmonic alternating traction current combined with power line locomotive converter. presence a complex leads to errors in decision-making regarding regulation train traffic. This puts participants this movement before danger threatening emergencies. Therefore, it necessary develop study means noise-immune reception formation dispatch decisions. decision on or absence signal made by comparing two values mean square approximation error. error understood as difference between input voltage receiver sum determined value calculated assuming mixture second assumption that there no mixture. noise assumed be present both cases. solution corresponds channel lower squared block diagram presented. Analytically, shown average recognizing situations orders magnitude less than admissible according regulatory requirements. High immunity developed will improve safety traffic
