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 and visualize them on 3-D display maps.
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 SISO and MIMO channels that have Rayleigh, Rician, or WINNER II fading profiles. Atmospheric impairments and multiple Doppler spectrum shapes are also available.
