Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics.

Abstract

This paper describes Complementary Code Keying with Differential Quadrature Phase Shift Keying (CCK+DQPSK) modulation, as used, for example, in the IEEE802.11b standard, and Gaussian Freuqnecy Shift Keying (GFSK) modulation, as used, ofr example, in the the Bluetooth standard. It indicates how the different types of modulation schemes might be more efficiently integrated to produce a modem capable of working with either modulation scheme. The paper presents a novel Multi Mode integrated Modem architecture, making use of: 1) programmable soft circuits 2) adaptive switching 3) adaptive FIR configuration 4) adaptive FIR functionality (same FIR, different function, e.g. correlation/matched filtering) 5) extended look-up table functionality Results are presented, indicating the performance of the integrated modem. Finally, implementation issues are discussed together with a way forward for further work in this area.
