By utilizing the common sparsity between different subcarriers and the dual structure sparsity of the angle cascaded channel matrix, the work [18] proposed a data-driven cascaded channel estimation method to accurately detect channel support using denoising neural networks. This work introduced deep ...
Although UAV-RIS-assisted URLLC systems have the potential to revolutionize wireless networks, providing more efficient, reliable, and innovative solutions for future communication networks, these systems are still in their early stages of development. In [25], joint optimization of UAV placement, RIS...
An energy efficiency maximization problem is formulated by satisfying the constraint of power budget, the design principles of RSMA and RIS. To solve this problem, fractional programming is first used to decouple the single ratio objective function. Then the optimal power allocation coefficients and ...
