Abstract: A mm-wave 2×2 antenna subarray is structurally packaged with a beamforming integrated circuit (BFIC) chip using laser-enhanced direct print additive manufacturing (LE-DPAM). Unlike prior art ...
If you pass by a café that operates a Wi-Fi network, you can be identified—even if you do not carry a smartphone with you. Researchers at Karlsruhe Institute of Technology (KIT) have found out that it ...
Abstract: In this paper, we study the downlink precoding of spatial non-stationary (SnS) extremely large-scale multiple-input multiple-output (XL-MIMO) in the near-field channel with uniform spherical ...
Massive MIMO and beamforming are essential technologies enabling 5G's current success and will be critical for achieving 6G's ambitious performance goals and applications. So, you want to create a ...
Bug: A naive solution may try all subarrays using nested loops (O(n²) or worse), which is too slow for large inputs. Expected: Use Kadane’s Algorithm (O(n)), which efficiently updates the running sum ...
Base station transmitter beamforming and beamsteering are effective methods of increasing base station coverage and capacity. These techniques require multiple transceivers and the baseband processor ...
