Beam Squint Calibration With Forced-Descent Sampling for Mobility-Aware Sensing in the Near-Field Massive MIMO Systems
The evolution toward 6G networks brings near-field propagation, wideband beam squint, and mobility-induced Doppler effects to the forefront of integrated sensing and communication (ISAC). These phenomena impose stringent requirements on estimation accuracy and algorithmic efficiency in massive MIMO systems. This paper...
