Interference suppression in spread spectrum communication systems is often essential for achieving maximum system performance. Existing interference suppression methods do not perform well for most types of nonstationary interference. We rst consider interference suppression schemes based on adaptive orthogonal time-frequency decompositions, such as wavelet packet and arbitrary dyadic time-freq...

This chapter presents joint interference suppression and power allocation algorithms for DS-CDMA and MIMO networks with multiple hops and amplify-and-forward and decodeand-forward (DF) protocols. A scheme for joint allocation of power levels across the relays and linear interference suppression is proposed. We also consider another strategy for joint interference suppression and relay selection...

The low transmission power and very large bandwidth used by Ultra-Wide band (UWB) radio systems ,enables them co-exist with other narrow-band systems over the same frequency band without interfering the narrow-band systems. Nevertheless, the interference caused by these narrow-band systems may jam the UWB receiver. Existing narrow-band interference suppression methods for spread spectrum system...

Antenna arrays with space-time adaptive processing (STAP) have been widely used in Global Navigation Satellite System (GNSS) to suppress interference in spatial domain as well as temporal domain, its performance depends on digital beamforming algorithms. In this paper, we propose a joint adaptive beamforming algorithm which produces nullings in the directions of interference while simultaneousl...

Improved radio frequency interference suppression method based on short time Fourier transform applied to synthetic aperture radar is proposed in this paper. The radio frequency interference, including narrow-band interference and wide-band interference, are analyzed in time frequency domain. The interference is identified at instantaneous frequency spectrum by a novel threshold criterion in ti...

Multi-classifiers are widely applied in many practical problems. But the features that can significantly discriminate a certain class from others often deleted feature selection process of multi-classifiers, which seriously decreases generalization ability. This paper refers to this phenomenon as interclass interference multi-class problems and analyzes its reason detail. Then, summarizes three...
