Spectral Coexistence of Unmanned-Aircraft Control Links And L-Band Navaids: A 3d Whitespace Analysis
Publikováno v:
2020 Integrated Communications Navigation and Surveillance Conference (ICNS).
This paper describes a capability developed to analyze 3-dimensional (3D) whitespace opportunities for enabling spectral coexistence of a secondary radio frequency (RF) system in a frequency band with primary RF systems that must be protected against
This small set of 3 titles, was first published in 1980 and 1987. The three volumes make important contributions to the study of cognitive process analyses of aptitude; learning and problem-solving; and conative and affective aspects of human perform

The amount of radio spectrum available for command and control (C2) radio links of unmanned aircraft (UA) systems (UAS), and the effectiveness with which that spectrum is used, will strongly affect the eventual number of remotely piloted UAS that can

Preventing interference among mobile radio (MR) nets often requires spectrum managers to observe channel-assignment rules based on minimum ratios of the great-circle distances traversed by desired and undesired (potentially interfering) signals. Find
