Adaptive Antenna Array Receivers for Spread-Spectrum Signals in Non-Gaussian Noise
We consider the problem of recovering a spread-spectrum (SS) signal in the presence of unknown highly correlated spread-spectrum interference and impulsive noise. In terms of basic system and signal model considerations, we assume availability of a narrowband adaptive antenna array that experiences additive white Gaussian noise in time and across elements, as well as impulsive disturbance with ...
متن کاملJoint Power Adjustment and Interference Mitigation Techniques for Cooperative Spread Spectrum Systems
This paper presents joint power allocation and interference mitigation techniques for the downlink of spread spectrum systems which employ multiple relays and the amplify and forward cooperation strategy. We propose a joint constrained optimization framework that considers the allocation of power levels across the relays subject to an individual power constraint and the design of linear receive...
متن کاملIST - 4 - 027756 WINNER II D 4 . 7 . 3 v 1 . 0 Smart antenna based interference mitigation
In this deliverable, smart antenna based interference mitigation methods for WINNER are presented. These methods include beamforming techniques, transmit diversity techniques, and receive diversity and spatial interference suppression techniques. The methods are investigated in terms of what requirements they put on the system, and the performance they can achieve are assessed by means of compu...
متن کاملSMART ANTENNA –AOA ESTIMATION EMPLOYING MUSIC ALGORITHM And DIGITAL BEAMFORMING By VARIABLE STEP-SIZE LMS ALGORITHM With NOVEL MAC PROTOCOL For IEEE 802.11
Smart antenna using multiple antennas exploring the SDMA technology has been used in wireless communication systems which provides higher spectrum efficiency, improved link quality and throughput through frequency reuse, reduction of intersymbol interference (ISI) and co-channel interference rejection (CCI)[1]. Space Division Multiple Access, where multiple user signals are simultaneously trans...
متن کاملSpoofing Mitigation of GPS Receiver using Least Mean Squares-Based Adaptive Filter
The Global Positioning System (GPS) signals are very weak signal over wireless channels, so they are vulnerable to in-band interferences. Therefore, even a low-power interference can easily spoof GPS receivers. Among the variety of GPS signal interference, spoofing is considered as the most dangerous intentional interference. The spoofing effects can mitigate with an appropriate strategy in the...
