| Description | This research has identified novel approaches to save energy in millimetre wave communications systems. Key points of study include: 1) Developing energy efficient methods for learning the wireless channel, so that it can be used by the transmitter and receiver to achieve maximum data throughput. 2) Novel approaches to operate the transmitter and receiver in order to maximise the energy per bit for communication. 3) New signal processing algorithms that provide robust reception for low complexity Rotman lens antennas developed by our project partner, Queens University of Belfast. |
| Exploitation Route | Our research is being published in conferences and journals to disseminate the findings to the scientific community. We also met with our advisory board in October 2018 and their recommendations led directly to a substantial collaboration between Dr Evangelos Vlachos from Edinburgh and Dr Babar Abbasi from Queens University Belfast. This work has led to new research papers that explore the impact of real world antennas on our signal processing algorithms. We met again in June 2019 to discuss our research with the advisory board and this has led to further avenues of research that we are exploring. We have closely collaborated with Dr George Alexandropoulos who was working with Huawei in France and with Prof Chatzinotas' group at the University of Luxembourg. These links have led to substantial co-authored journal papers being published. |

| Description | The project RA, Evangelos Vlachos collaborated closely with George Alexandropoulos, who was working with at the Paris Research Centre, Huawei Research Laboratories, France. George Alexandropoulos provided guidance on technical direction for Evangelos' research and also reviewed the papers that he wrote afterwards. George became the co-author of four papers written during the project, two conference and two journal papers. This collaboration will have influenced research and development work carried out at Huawei Research Laboratories in Paris, France. |
