RF Propagation and Channel Models
RF path propagation modeling describes the behavior of electromagnetic radiation from a point of transmission as the signal travels through the surrounding environment. Model RF propagation paths to calculate signal propagation through atmospheric gases, rain, fog and clouds, and tropospheric scintillation. You can also calculate outage probability due to rain attenuation with site diversity.
Channel modeling describes the over-the-air environment in communications system links. Analysis of propagation and channel modelling is essential in understanding how electromagnetic waves incur losses from a transmitter to a receiver in different scenarios. Model and visualize noisy single input single output (SISO) channels that have Rician or Land Mobile Satellite (LMS) fading profiles.
