Digital twin for pre-screening users in MU-MIMO downlink

US & West ·

The DiTUS framework uses a digital twin to pre-screen promising users before instantaneous CSI acquisition in MU-MIMO systems. Spatial covariances are formed from estimated departure angles and path powers, with optional calibration to mitigate bias. Candidates are selected via a projection-energy rule (DiTUS-P) or a greedy log-determinant rule (DiTUS-L).

Why it matters

The method improves efficiency of user scheduling in dense networks, which is important for digital twins of telecom systems.

Parallel branch MPC on GPUs

A GPU-based solver for trajectory planning problems using branch model predictive control is presented. The solver is based on iterative LQR, multiple-shooting formulation, and augmented Lagrangian method for constraint handling. Numerical experiments show superiority over a CPU-based solver on large-scale problems.
