Abstract
A method for eliminating interference signals in a direct sequence spread spectrum link involves frequency detection of interference signals by comparison of the spectrum of the composite input signal with a threshold and filtering of the composite input signal by a finite impulse response filter using rapid convolution. The detection of threshold is automatically controlled by using an estimate of the spectral input density after eliminating large interference signals.
