Analyzing the performance of error-prone relay networks
In this paper, we provide a semi-analytical method for predicting the upper and lower bound of the end-to-end mutual information for a relay network with practical codes and diffe...

Widely distributed MIMO radar beamforming for detecting targets with slow RCS fluctuations
In a widely distributed MIMO radar, the transmitters and the receivers are distributed so that they see a target from different aspects. The scattering from the target is therefor...

A fast projected gradient optimization method for real-time perception-based clipping of audio signals
Clipping is a necessary signal processing operation in many realtime audio applications, yet it often reduces the sound quality of the signal. The recently proposed perception-bas...

From direction of arrival estimates to localization of planar reflectors in a two dimensional geometry
In this paper we propose a novel technique to localize planar obstacles through the measurement of the Direction of Arrival by a microphone array. The measurement of the Direction...

Keypoint-based near-duplicate images detection using affine invariant feature and color matching
This paper presents a new keypoint-based approach to nearduplicate images detection. It consists of three steps. Firstly, the keypoints of images are extracted and then matched. S...
