Air-to-Ground Wireless Links for High-Speed UAVs
TL;DR: This paper designs robust A2G wireless links for high speed UAVs, where conjunct power control is developed together with switched beamforming to maximize the power efficiency and minimize the fluctuation of A2g wireless links of millimeter wave (mmWave) signal transmission.

Rate Splitting on Mobile Edge Computing for UAV-Aided IoT Systems
TL;DR: A joint rate splitting problem is formulated to optimally allocate rates for transmission links between two antenna arrays on the UAV to minimize the energy consumption of a UAV in the centralized and distributed MEC computation modes under the constraints of transmission rate and computational time.

Large-Scale MIMO Detection Using MCMC Approach With Blockwise Sampling
TL;DR: Complexity analysis and simulation results show that the proposed approach outperforms the conventional LR-based Klein randomized successive interference cancellation (SIC) detection with a relatively low complexity.

UAV-Aided Backscatter Communications: Performance Analysis and Trajectory Optimization
TL;DR: A signal detection approach based on the central limit theorem to detect the presence of parasite devices and separate parasite signals from host signals is proposed and the trajectory planning of multiple UAVs is optimized.

Multiple Delay Estimation for Collision Resolution in Non-Orthogonal Random Access
TL;DR: This paper focuses on the estimation of round-trip delays (RTD) of multiple signals in non-orthogonal random access (NORA) based on the maximum likelihood (ML) criterion and proposes a low-complexity approach based on variational inference, which is widely used in machine learning.
