Rank and Condition Number Analysis for UAV MIMO Channels Using Ray Tracing

Lee, D., & Guvenc, I. (2023, June 1). 2023 IEEE 97TH VEHICULAR TECHNOLOGY CONFERENCE, VTC2023-SPRING.

By: D. Lee n & I. Guvenc n 

author keywords: AERPAW; condition number; drone; MIMO; channel rank; ray tracing; spatial multiplexing; UAV
topics (OpenAlex): Millimeter-Wave Propagation and Modeling; UAV Applications and Optimization; Advanced MIMO Systems Optimization
TL;DR: Detailed ray tracing simulations are used to characterize how the channel rank tends to reduce as a function of UAV altitude, while also providing insights into the effects of geography, building distribution, and threshold parameters on channel rank and condition number.
