文摘
- •
Less spatial-correlated secondary users (SUs) are selected based on Hungarian method.
- •
The joint optimization of sensing time and transmission power of SUs is achieved through Novel Iterative Dinkelbach method (NIDM) algorithm.
- •
The combination of parametric transformation with the Lagrangian duality provides better performance with lesser computational complexity.
- •
The proposed method is validated through the simulation results.
