Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

This paper compares two different filter bank multi carrier (FBMC) modulations: a critically sampled and therefore spectral maximally efficient FBMC orthogonal quadrature amplitude modulation (OQAM) approach, as well as an over sampled (OS)-FBMC system. Under a dispersive channel, FBMC/OQAM and OS-FBMC require equalisation and timing synchronisation, which here is accomplished by a fractionally spaced equaliser updated by a concurrent constant modulus and decision-directed algorithm. Simulation demonstrate that FBMC/OQAM is more difficult to equalise particularly at lower SNR, since its additional CCI terms amplify the equalisation algorithm’s gradient noise.
