Radar sensor networks, including biand multi-static radars, provide several operational advantages, like reduced vulnerability, good system flexibility and an increased radar cross-section. However, radar-to-radar interference suppression is a major problem in distributed radar s
Narrowband Interference Suppression in Spread Spectrum Communications
Due to the scarcity of frequency allocations for emerging personal communications services, it has been proposed that spread spectrum (SS) signals be used in such services so that they can be overlaid on existing frequency band occupants. Such SS signals would be constrained in p
Blind Adaptive Interference Suppression For Direct-sequence CDMA - Proceedings of the IEEE
Direct sequence (DS) code division multiple access (CDMA) is a promising technology for wireless environments with multiple simultaneous transmissions because of several features: asynchronous multiple access, robustness to frequency selective fading, and multipath combining. The
Code-Aided Interference Suppression for DS/CDMA Overlay Systems
The push toward more efficient and flexible use of the radio spectrum has led to the consideration of the overlay of spread-spectrum (SS) communication networks on preexisting narrow-band networks. Such systems are already in widespread and rapidly expanding use in the lightly re
Joint Source-Relay Precoding with MMSE-based Interference Suppression in two-way MIMO Amplify and Forward Relays
In this paper, we consider a two-way multiple input multiple output (MIMO) Amplify-and-Forward (AF) relay system, where interference is observed at the relay node during the multiple access (MAC) phase. For such a scenario, two new joint source-relay precoding algorithms with int
Performance of adaptive linear interference suppression in the presence of dynamic fading
Adaptive linear interference suppression for directsequence (DS) code-division multiple access (CDMA) is studied in the presence of timeand frequency-selective fading. Interference suppression is achieved with an adaptive digital filter which spans a single symbol interval. Both
Transform Selection Metrics for Interference Suppression
Interfering signals are a common nuisance in wireless communications and may cause performance loss. In addition, overlay systems where non-spread and spreadspectrum systems coexist will become more common in the future. Therefore, the need for versatile interference suppression
Interference Suppression Using Principal Subspace Modification in Multichannel Wiener Filter and Its Application to Speech Recognition
© 2010 Gibak Kim 921 It has been shown that the principal subspace-based multichannel Wiener filter (MWF) provides better performance than the conventional MWF for suppressing interference in the case of a single target source. It can efficiently estimate the target speech compon
Interference Suppression in Diversity Wireless Receivers via ICA with Individual Adaptations
In this paper, a novel Independent Component Analysis (ICA) algorithm is proposed with application to interference suppression in diversity receivers. For mobile and wireless communications, the new technique is an efficient baseband digital interference rejection method that res
Digital Receiver with Interference Suppression for Microwave Radiometry
A new receiver architecture for use in L-band microwave radiometers is proposed. The receiver is based on analog-to-digital conversion of a significant bandwidth of received emissions, and includes sufficient dynamic range so that digital processing can be performed to remove at
