FM interference suppression in spread spectrum communications using time-varying autoregressive model based instantaneous frequency estimation
In case of a strong frequency modulated interference in a spread spectrum communication system, the interference can be effectively suppressed by applying a time-varying notch filter with its zero(s) placed at an instantaneous frequency (IF) estimate of the interference. In this paper, we present the use of a timevarying autoregressive model based IF estimator in such a scenario. We model the r...

متن کاملInterference Rejection Techniques in Spread Spectrum Communications
Spread spectrum communication systems have many applications, including interference rejection, multiple accessing, multipath suppression, low probability of intercept transmission, and accurate ranging. Of all the potential applications, the ability of a spread spectrum system to withstand interference, both intentional and unintentional, is probably its greatest asset. Of course, any spread s...
متن کاملInterpolation Lattice Filters for Narrowband Interference Cancellation in PN Spread Spectrum Communication Systems
Previous work on the adaptive lattice filters for narrowband interference rejection in a direct sequence (DS) spread spectrum communication system has centered around the use of one-sided prediction only. For two-sided interpolation, that is known to achieve better interference rejection than its one-sided counterpart, only the least-mean-squared (LMS) algorithms have been considered thus far i...
متن کاملOn SNR as a measure of performance for narrowband interference rejection in direct sequence spread spectrum systems
The usefulness of SNR as a figure of merit to quantify the narrowband interference rejection capability of a DS receiver is examined. The interference considered is a peaked autoregressive Gaussian process. The probability of error and SNR estimates of a Kalman, a modified Kalman, and a nonlinear filter proposed in [2] are obtained by simulation. Based on this simulation study and the available...
