WebApr 12, 2024 · The simulations presented therein covered the entire flow field, extending from the near field around a supersonic aircraft to the far field reaching the ground. The simulation [ 7 ] has been performed by solving the three-dimensional Euler equations with a gravitational source term for maintaining hydrostatic balance in a stratified atmosphere. WebJan 26, 2024 · Extremely large-scale multiple-input-multiple-output (XL-MIMO) is promising to meet the high rate requirements for future 6G. To realize efficient precoding, accurate channel state information is essential. Existing channel estimation algorithms with low pilot overhead heavily rely on the channel sparsity in the angular domain, which is achieved …
