Abstract: 4D millimeter-wave radar has gained attention as an emerging sensor for autonomous driving in recent years. However, existing 4D radar and camera fusion models often fail to fully exploit ...

Abstract: A nonlinearity-tolerant geometrically-shaped four-dimensional (4D) modulation format, NL-4D-1024, with spectral efficiency (SE) of 10 bit/4D-sym is designed. Numerical simulations for a ...

This program visualizes a 4-dimensional tesseract (hypercube) in a 3D space, using pygame and numpy to handle the graphics and calculations. The tesseract can be interactively rotated on multiple axes ...
