6G Green IoT Network: Joint Design of Intelligent Reflective Surface and Ambient Backscatter Communication
Algorithm 1
Transmit beamforming vector optimization.
1:Initialize: random IRS phase shifts ; random backscatter coefficients ; | 2:Optimize problem (P4) by CVX and get . | 3:Get and , where | 4Get , where is uniformly distributed on the unit sphere. | 5:Scaling so as to satisfy constraints (14b)–(14d). |
