Interference 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 کاملAdaptive beamforming system for radio-frequency interference rejection
8MHzBP filter at -Q+ bandpass 70 MHz filter Abstract: Results from an experimental antenna array that is processed adaptively to cancel external radio-frequency interference are presented. The eight-element array has been tested in a far-field anechoic chamber. The adaptive beamformer rejects sidelobe and main-lobe interference by up to 37 dB. A conventional Fourier beamformer rejects interfere...
متن کاملRobust Algorithms for DOA Estimation and Adaptive Beamforming in Wireless Mobile Communications
This paper presents a tool for the modelling, analysis and simulation of direction-of-arrival (DOA) estimation and adaptive beamforming needed in the design of smart antenna arrays for wireless mobile communications. The developed tool implements the Minimum Variance Distortionless Response (MVDR) algorithm for DOA estimation and the Least Mean Squares (LMS) algorithm for adaptive beamforming. ...
متن کاملInterference Rejection in Impulsive Noise for VLF Communications
The use of frequency-shift (FRESH) filtering for the rejection of adjacent channel interference (ACI) in GMSK modulated VLF communications is investigated in the presence of impulsive noise. The effects of such filtering in conjunction with a simple “hole-punching” technique for removing impulses from the signal are characterised. A range of realistic scenarios based on a high powered GMSK inte...
متن کاملInterference cancellation beamforming robust to pointing errors
The conventional Wiener–Hopf beamformer is subject to substantial performance degradation in the presence of steering vector pointing errors. By removing the effects of the desired signal, the modified Wiener–Hopf beamformer avoids this problem but allows cochannel interferences to pass through in order to maximise the signal-to-noise ratio. In this study, a novel array beamformer is proposed, ...
