Strathprints makes available scholarly Open Access content by researchers in the Department of Architecture based within the Faculty of Engineering.

Research activity at Architecture explores a wide variety of significant research areas within architecture and the built environment. Among these is the better exploitation of innovative construction technologies and ICT to optimise 'total building performance', as well as reduce waste and environmental impact. Sustainable architectural and urban design is an important component of this. To this end, the Cluster for Research in Design and Sustainability (CRiDS) focuses its research energies towards developing resilient responses to the social, environmental and economic challenges associated with urbanism and cities, in both the developed and developing world.

In this paper, we explore the influence of oversampling on a filter bank based transmultiplexer, for which previous research has established oversampling as a useful mean to ease synchronisation. The effect of oversampling is assessed mainly in terms of inter-symbol interference due to synchronisation errors and due to the residual time-dispersive effect of the transmission medium after transmultiplexing. Both effects can be targetted by a fractionally spaced equaliser. Although the achievable minimum mean square error is lower for higher oversampling ratios, we show by example of a powerline communications channel that slow convergence of least mean square type adaptive equalisers prohibits the exploitation of this benefit. Together with considerations on bandwidth efficiency and peak-to-average power ratio, it is advantageous to keep the oversampling ratio as small as possible.
