Cooperative Back-haul Aided Next-Generation Digital Subscriber Loops
To meet the demand of exponentially growing tele-traffic and to sustain the current level of economical growth, a high-quality digital infrastructure based on innovative and cost efficient solutions is required. The current geo-economics and building-preservation of historic cities do not favour the pervasive penetration of fibre. Hence, a lower-cost solution based on the improved exploitation of the existing copper network is essential to facilitate transformation of the digital infrastructure to support the next evolutionary step to Giga bits/s data rates. However, experts from our industrial partner BT believe that the throughput achieved with the aid of the state-of-the-art copper technology may only represent less than 30% of its ultimate capacity, when we exploit the hitherto unexploited high-frequency band. Hence, the research of next-generation ultra-high-throughput DSL systems beyond G.fast becomes of crucial importance and timely, where radically new signal processing techniques have to be conceived.
The challenge is to conquer the entire Very High Frequency (VHF) band and to holistically design the amalgamated wire-line and wireless system considered. Our proposed research starts from the fundamental understanding of the DSL channel over the entire VHF and beyond into UHF (up to 500 MHz) bands to the design of radical signal processing techniques for tackling the critical challenges. Holistic system optimisation is proposed for exploiting the full potential of copper. Thanks to BT's huge support, our proposed research has a high immediate engineering impact and a long-term scientific adventure.

Les Humphrey obtained B.Sc. in Electrical Engineering, and ACGI, from Imperial College London University, 1970, M.Sc. in Telecom Switching from Aston University Birmingham 1974. Joined ITT/STL in 1970 working on modulation for digital microwave links and very high speed baseband digital transmission on coax for trunk applications. Worked on DSP and A to D aspects including Si implementation from 1978 till 2001 for ITT/STL/STC/Nortel. Was technical lead for projects including Trans-Multiplexer, various speech and image processing projects, software defined radio, A to D and D to A technology, formal methods for Si design, EMC aspects of digital transmission, and digital transmission on copper pairs from ISDN basic rate access to VDSL. Joined BT in 2001 as Chief Researcher with responsibility for leading DSL Research and Standards activities related to DSL, including work on ADSL, VDSL2, and in the past 5 years focusing on the G.fast concept both DSP and systems aspects.
Dr Paul Botham, Senior Research Engineer, Research & Innovation, BT. Paul Botham joined BT with a D.Phil. in theoretical physics from Oxford University. Within Research and Innovation, he has worked in a variety of network modelling roles, applying mathematical techniques to develop software tools for designing least-cost, resilient BT networks. This has involved a wide range of technologies in both core-transport and access environments. Paul is currently working on optimised deployment of next-generation network technology, incorporating both modelling of high-frequency propagation in copper cables and risk analysis for BT business cases.Work Plan
