Communications

Communications systems are fundamental to our lives and underpin the internet which is becoming increasingly ubiquitous.

Our programme of research tackles both theoretical and fundamental communications problems as well as more practical issues of implementing and improving communications systems. Our work addresses a wide range of technologies including wireline, radio frequency and optical communications systems, as well as improving communications interfaces.

Our research will impact practically in the following ways:

  • Efficient and higher bandwidth communications technologies to tackle the rapidly increasing demand for internet traffic
  • Lower energy consumption technologies that reduce the carbon footprint of future communications networks
  • Seamless and secure communications technologies and interfaces to improve the quality of human life

Recent Research Advances

  • Developed a new "spatial modulation" technique for MIMO systems
