The present paper proposes and studies an algorithm to estimate chan- nels with a sparse common support (SCS). It is a generalization of the classical sampling of signals with Finite Rate of Innovation (FRI) and thus called SCS-FRI. It is applicable to OFD ...
Ultra wide band (UWB) may offer very efficient solutions for various communication and sensing applications. Two approaches have emerged, which meet all the communication requirements: impulse and multi-band systems. The present work is concerned in the se ...
Physical impairments like IQ imbalance and phase noise can cause significant degradation in the performance of wireless communication systems. In this paper, the joint effects of IQ imbalance and phase noise on OFDM systems are analyzed, and a compensation ...
Energy-detection receivers are appealing to IEEE 802.15.4a low data-rate networks because of their low complexity. With a reasonable energy consumption, these receivers can exploit the ranging capabilities and multipath resistance of impulse-radio UWB (IR- ...
It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...
Given uncertainty in environment, a conservative approach is to design for the worst case, leading to a game-theoretic situation where the environment is controlled by an adversary. However, in many cases, the uncertainty arises from randomness, not an adv ...
This paper describes the implementation of the hard computational kernels required for the baseband (BB) processing of a 2×2 multiple-input multiple-output (MIMO)-OFDM receiver on a design-framework for application specific processors. The employed low-com ...
We demonstrate that an interferer with malicious intentions can significantly degrade the performance of impulse radio (IR) ranging. The cicada attack we have developed can decrease the distance (degradation of service) measured by ranging algorithms desig ...
Wireless adhoc networks consist of users that want to communicate with each other over a shared wireless medium. The users have transmitting and receiving capabilities but there is no additional infrastructure for assisting communication. This is in contra ...
Energy-detection is appealing for IEEE 802.15.4a receivers as it allows to exploit the ranging capabilities and the multipath resistance of impulse-radio UWB at a reasonable complexity. IEEE 802.15.4a receivers operate with interference created by uncontro ...
