Improving link quality of UWB communication links by means of PSWF-Basis persuit denoising

Wireless Body Area Networks (WBANs) utilising Ultra Wideband communication channels often use a combination of thin sensor nodes and a heavy base node. The sensor nodes need to be as simple and low power as possible. This makes it difficult to maintain a good quality link. In this paper additional post processing steps at the base node are proposed in order to overcome these issues. A basis persuit denoising technique, using Prolate Spheroidal Wave Functions (PSWFs), combined with a sampling technique inspired by compressive sensing allows data to be recovered even when the link is interrupted for short intervals.
