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.
Site Viewer basics, basemaps, and troubleshooting.
When you start Site Viewer up on showing a txsite or rxsite object, a check is made to make sure that you have an internet connection to retrieve the default basemap and terrain data.
Access Basemaps and Terrain in Site Viewer
To download MATLAB® basemaps:In addition, Site Viewer also supports three external basemaps that you can select from the basemap picker.
When to use the different propagation models based on frequency, type, and limitations.
Model channel and RF impairment characteristics.
Configure Eb/No for AWGN Channels with Coding
This example shows how to set the bit energy to noise density ratio (Eb/No) for communication links employing channel coding.
Using AWGN Channel Block for Coded Signals
Two links perform error control coding on a signal that has passed through an impairment channel.
