Impulse-radio ultra-wideband (IR-UWB) radios are slated to be the next generation of
transceivers that can support power-constrained applications such as wireless sensor and …

Sampling is the bottleneck for ultra-wideband (UWB) communication. Our major contribution
is to exploit the channel itself as part of compressed sensing, through waveform-based pre …

Dynamic spectrum access is a must-have ingredient for future sensors that are ideally
cognitive. The goal of this paper is a tutorial treatment of wideband cognitive radio and radar …

Ultra wideband (UWB) technology is suitable for high data rate short range wireless
communication, localization, and imaging techniques. However, UWB systems require high …

We propose a novel receiver for Ultra-Wide-band Impulse-Radio communication in Wireless
Sensor Networks, which are characterized by bursty traffic and severe power constraints …

To cope with the formidable sampling rate required by Nyquist criterion, compressive
sensing (CS) has been recently adopted for ultrawideband (UWB) channel estimation. In this …

The emerging theory of compressed sensing (CS) enables the reconstruction of sparse
signals from a small set of random measurements [1],[2]. Since CS samples the signals at …

This paper addresses the problem of joint time of arrival (TOA) and direction of arrival (DOA)
estimation in impulse radio ultra‐wideband systems with a two‐antenna receiver and links …

Compressive sampling (CS) based energy detectors are developed for ultra-wideband
(UWB) pulse position modulation (PPM), in multipath fading environments so as to reduce …

Operating at sub-Nyquist rate, compressed sensing (CS) has been successfully applied to
the design of impulse ultra-wideband (I-UWB) receivers where Nyquist sampling is a …
