METHOD AND APPARATUS FOR ADJUSTING THRESHOLD WEIGHT OF FREQUENCY DOMAIN TO IMPROVE ANTI-JAMMING PERFORMANCE AND ELIMINATE JAMMING IN GPS SYSTEM

摘要

A method and apparatus for improving anti-jamming performance are provided. A threshold value level estimated in a GPS (global positioning system) receiver RF/IF stage, a threshold value weight, a median value of a median value of a 2~8MHz bandwidth is estimated as a threshold value with respect to a frequency component exceeding the estimated threshold value level, and an adjustable K-median threshold scheme is provided in a multi-jamming environment.
