Advanced Signal Generation And Detection System For Next-generation Ultra-wideband Communication Networks
Lead Research Organisation:
University College London
Department Name: Electronic and Electrical Engineering
Abstract
The research is focused on one of our society's greatest technical challenges and economic drivers with impact on knowledge, economy, society and people as well as business and government activities. It aims to transform the development of the information and communication infrastructure. A high-capacity, flexible, cost-effective and efficient telecommunications and data infrastructure is of great national and international importance. The ability to communicate seamlessly, without delay, requires intelligent communications networks with high capacity, available when and where it is needed. To achieve this requires research advances in ultrawideband wireless and optical networks, as well as intelligent transceivers, new ultrawideband optical devices and algorithms. This is a fast-moving and internationally fiercely competitive field and to maintain international leadership requires the capability of not only making theoretical advances, but the also the ability of demonstrating these experimentally.
Our vision is to create an advanced, world leading signal generation and detection test-bed for advanced communications systems research. The key feature of the proposed system are the ultra-low noise, high-resolution capture and analysis of complex broadband signals, more than quadrupling the achievable network capacity. This unique facility will allow the investigation of optical and wireless networks over a wide range of time- and length scales, including long-haul networks, data centres and enable the research into the ultra-wideband signal manipulation for the next-generation optical & wireless access networks. It will enable UCL and UK to consolidate and enhance its internationally leading position in communications systems research supporting a wide range of other areas.

| Description | - Enormous progress made despite COVID19 disruptions - Carried out rigorous procurement procedures purchasing, installing and testing 110 GHz Keysight UXR oscilloscope - Specified and procured/set up and tested 110 GHz optical receiver, establishing effective collaboration with Heinrich Hertz Institute - Specified and ordered high-performance DACs/arbitrary waveform generator to enable world-leading experimental set up to be achieved - Studied the comparison of probabilistically and geometrically shaped constellations in transmission over varying transmission distances - Achieved a world-leading result 8× 26 GBd DP-GS256QAM super-channel transmission with a net data rate of 2.29 Tb/s - received after 75 km transmission using a single 211-GHz optical receiver. The use of digital pre-distortion and tailored geometric constellation shaping led to an improvement of 1.2 bit/4D-sym in the achievable information rate. - A demonstration of this signal generation and detection and its integration with the National Dark Fibre Facility was demonstrated recently at the Optical Fibre Communication Conference in San Diego in March 2023. - Results of all experiments have been fed into the TRANSNET Virtual Laboratory (TVL) database to be used for training of AI-based systems - Work is ongoing to design and develop |
| Exploitation Route | A high-speed test-bed is essential for next-generation, adaptive, low-delay, high-speed broadband & intelligent digital infrastructure. The test-bed is open to industry and academia in the UK and beyond for the testing of next-generation devices, systems and network concepts and there is expected to be significant take-up in this unique capabilities, both in UCL and remotely over the NDFF. |

| Impact | The white paper proposes with a number of recommendations. (1) to create a UK Long Term Telecommunications Research Strategy Forum to advise the Government on the long-term research priorities, opportunities and risks for the telecommunication domain; (2) to create a National Centre for Translational Telecommunications Research; (3) to create a funding framework that incentivizes collaboration-for-impact excellence alongside competition-for-excellence, and finally; (4) to develop recommended frameworks and approaches to help lower the barriers to collaboration between academic institutions and industrial exploitation of academic research. Putting these into practice will improve the digital communications infrastructure and the continued R&D to sustain its development! |

| Results and Impact | Telecommunications, Optics and Photonics (TOP) Conference, took place in London from 14-15 February in London and attendees were able to find out about the latest trends in photonic integration; silicon photonics using InP, GaAs and polymer solutions; packaging solutions; hybrid integration; lasers, modulators and receivers; filters and switches and connectors. Held in Bishopsgate, London, close to Liverpool St station, the conference allowed delegates and speakers valuable in-person networking opportunities as well as time to view the poster sessions. Along with the comprehensive programme, the conference featured two workshops: UK capabilities in photonics (& new allied technologies): current status, demands and drivers, future prospects, and opportunities for growth - which reviewed the current status of UK capabilities in photonics considering present societal demands and business drivers, and examined future prospects for photonic technologies and new opportunities for short, medium, and long-term growth. UKRI Hubs & Programme Grants: recent progress in optical communications, photonic technologies, quantum communications and quantum computing - this workshop brought together world-leading researchers to exchange the latest results, ideas and to explore new opportunities for cross-fertilisation and co-working across these research fields. Over 10 research posters as well as a presentation on the TRANSNET Programme Grant. |

| Results and Impact | WAVE 2022 was a one-day conference held at the BT Tower, sponsored by the Sub-Optic Foundation to attract young people to the field of subsea communications - and with prominent members of the sub-sea community - it was an important Advocacy event: https://wave.subopticfoundation.org/ TRANSNET team played a major role in the organisation of the event, and Professor Polina Bayvel was one of the prominent figures at the event. In addition to being one of the key speakers at the Round Table discussion on the range of opportunities available in Subsea, she also presented her thoughts on defining moments in the breakthrough of optical networks; followed by an engaging debate on the topic with Gary Waterworth, Network Investment EMEA at META and Maja Summers, Senior Submarine Commercial Manager at Vodafone. TRANSNET was also officially recognised as a partner of the event for supporting the organisers with planning of the event. The event was livestreamed to schools around the world, and was attended by both established and up-and-coming figures in the field of subsea communications. |
