This is the project submitted in fulfillment of requirements for the degree of MSc Communications and Signal Processing at Imperial College London.
- Communication and radar spectrum sharing
- Reconfigurable intelligent surface
- MIMO radar system
- MISO multi-user wireless communication system
- Weighted Minimum Mean Square Error (WMMSE) optimization framework [1]
- Fractional programming [2, 3]
- Semidefinite Relaxation (SDR) [4]
- To our knowledge, this is the first study of WSR maximising for a RIS-aided DFRC system.
- This is also the first work that investigates the novel group or fully connected RIS model [5] in RIS-aided DFRC.
- Two alternating optimization algorithms for the proposed non-convex beamforming design.
