Abstract-- Wideband communications are asymptotically impossible with signals that are spread over a very wide band and are transmitted over a multipath channel unknown ahead of ti...
This paper reports on the use of a twisted map digital chaotic sequence as a carrier signal in a COOK system. The sequence generated shows low cross-correlation properties with ve...

In this paper we consider the problem of sampling far below the Nyquist rate signals that are sparse linear superpositions of shifts of a known, potentially wide-band, pulse. This...
The availability of positional information is of great importance in many commercial, public safety, and military applications. The coming years will see the emergence of locationa...
Abstract – Jointly optimised iterative source- and channel-decoding is used for enhancing the error resilience of the Adaptive Multi Rate WideBand (AMR-WB) speech codec. The resu...
