1 Description
This document suggests a user’s guide to a MATLAB application which simulates a Spatial Channel Model
(SCM) based on reference [1] with some minor adjustments. It focuses on how to use the Graphical User
Interfaces (GUIs) and the functions of the application and avoids going into specifics about the nature of the
parameters as this is done analytically in the reference document. The user should at any point consult [1] for
additional information.
The MIMO spatial channel model simulates a wireless propagation channel in various cases and applies the
concept of diversity (spatial and polarization) assuming multiple antennas at both the transmitter and receiver,
thus forming a Multiple Input Multiple Output antenna system.
2 Scope
The scope of the present SCM application is to provide an easy-to-use MATLAB developed application to
any user who requires a practical tool to perform MIMO simulations and to obtain statistical data which can
be later further analyzed. Much effort was made so that all the parameters involved are user-selective,
something that allows this application to be flexible to any desired case.
