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. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

In order to satisfy the requirements and expectations of the user to have more advanced wireless communication in mobile environments, this paper outlines the technical issues involved in Beyond Third Generation (B3G) mobile communications, High-Speed large capacity transmission capability is an essential requirement for B3G mobile communications for which we suggest VSF-OFCDM, SCS-MC-CDMA, OFDMA and IFDMA, efficient modulation demodulation techniques to achieve higher spectral utilization efficiency (such as combination of OFDM with CDMA, error control coding using LDPC codes); wireless multi-system terminals with End-to-End Reconfigurability. Frequency allocation (of Europe) is a major issue in the performance (how much date rate it can offer with available bandwidth) of wireless networks.
