Engineering a better future
Associate Professor Sarah Johnson performs research in the fields of signal processing, error correction coding and information theory.
Centre for Secure and Reliable Communications
The Centre for Secure and Reliable Communications contributes to developing telecommunication networks that are robust to eavesdropping attacks, interference, and noise.
Research focuses
- Deriving fundamental limits for data transmission in multi-terminal communication networks
- Designing near-capacity codes for various communications channel conditions
- Developing transmission schemes that are information-theoretic secure (which are robust against attacks by quantum computers)
- Enhancing the network capacity by exploiting side information available at the devices
- Optimising and managing radio resources in 5G networks
- Designing protocols to securely distribute data-encryption keys through quantum channels
Research Projects
- Broadcast channel with side information
- Multi-edge-type low-density parity-check codes
- Index coding
- Near-capacity rateless codes
- Integrated Feedback Control in Future Wireless Communication Networks (with Ericsson)
- Secure index coding
- Quantum key distribution (with QuintessenceLabs)
