CDMA output results description
In order to make use to the full extent of the information provided by SEAMCAT GUI interface, the attached document(2 MB) presents and also provides the users with the information that can be extracted when conducting CDMA simulations.
This document is a guide document when using the CDMA module of SEAMCAT.
Note: Most of the information (i.e. graphics) in this document is based on SEAMCAT 3.2 but unless explicitly stated all elements are also available in version 3.1.x.
The CDMA GUI interface can be divided into four logical parts:
- Pre-simulation parts: This part of the GUI is used to assist the user when configuring the workspace. All CDMA specific GUI elements are available as part of either the Victim Link or the Interfering Link configuration dialogs.
- Simulation parts: Simulation GUI elements are shown during the simulation and are used to provide information about what SEAMCAT is doing. Since CDMA simulation can take much longer than “classic/traditional” (i.e. non-CDMA) SEAMCAT simulations there are special GUI parts used to provide information to the user.
- Results
- Detailed information on the last snapshot: After a simulation these GUI parts are used to provide access to calculated results but also detailed insight into the last snapshot of the simulation. Inspecting the last snapshot is considered a good way to validate the configuration of the simulated workspace.
This document is a complement to the user manual on the CDMA simulation algorithms that can be found at http://tractool.seamcat.org/wiki/Manual/Algorithms/CDMA which was a compilation of STG(03)12rev1 and STG(03)13rev1.
