The Efficiency of the Adaptive Filter for Suppression of a Harmonic Interference During the Reception of Modulated Signals with Continuous Phase

摘要

The influence of parameters of the adaptive rejector filter on the quality of reception of modulated signals with continuous phase (MCP signals) in the presence of noise and harmonic interference at the receiver input is analyzed. Both the coherent and autocorrelation signal processing algorithms are considered. Using the computer simulation, the probability of error in the discrete symbol reception is calculated as a function of the filter rejection band, signal-to-noise ratio, interference frequency and intensity, and signal modulation index.
