Abstract :
A novel technique for narrowband/broadband frequency selective limiting in direct sequence-spread spectrum (DS-SS) communications is presented. This technique relies on setting the magnitude response of the received signal Fourier transform to a predetermined function while leaving the phase response unchanged. When the Fourier transform magnitude response of the signal is made constant over the entire signal spectrum, this nonlinear processor will operate as a whitening filter
