A New Method for Estimating the Impacting of Interference on Digital Communication System
Yihua Hu · Modern Defence Technology · 2007
The paper puts forward an analytical low-complexity method for intersystem interference estimation among communication equipment.BEP is normally employed to estimate the function of the digital communication receivers but simplification is needed in computing and analyzing for the reason that the circumstances of the intersystem-interference via BEP are extremely complicated.The interference is often supposed to be AWGN,while in some cases it is not reasonable supposition.So the method based on HOS kurtosis is proposed.Integrating AWGN approximate and kurtosis measurement,it can deal with both modulated interference signals and impulse interference signals so as to achieve more accurate and reasonable analysis of the interference among digital communication equipment.
