Abstract
This article proposes a geometrically-based wireless channel model with limited Angle of Arrival (AOA). This model assumes that the line-of-sight (LOS) paths are obscured and scatterers are distributed within the scattering angle around a mobile station, resulting in the AOA received by the base station being limited to a certain range. Such a single bounce scattering models can be used for different 6G scenarios such as integrated sensing and communication (ISAC) and intelligent reflecting surface (IRS) by adjusting the angle parameter. Accordingly, the azimuthal angle and time of arrival marginal probability density functions (PDFs) are derived in closed form, which is evaluated in numerical simulation by compared to the normalized histograms. Finally, the proposed model is analyzed and verified with the measured data in micro and macro cells, which clearly demonstrates its accuracy and flexibility.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
