2.5 Create or update a simulation workspace

To start, you need either to create a new workspace (see 1 in Figure 25 or open an existing one (2). 

Figure 26: Illustration of how to create or open a workspace

A simulation scenario is a part of a scenario workspace, which defines all technical parameters of modeled links as well as some related modelling assumptions, such as physical (mutual) placement of transceivers, propagation modelling settings and so on. Within SEAMCAT a simulation scenario is based upon the concept of links. A link stands for a pairing of one transmitter with one receiver[1] operating together in a given radiocommunication system. Such a link is also called a “system link”.

When a new workspace is created, all of its scenario elements are populated with default values (representing a hypothetical interference case between two systems at 900 MHz, as shown in Figure 27). Therefore after creating a new workspace yourfirst step should be to review and modify the scenario parameters so that the resulting simulation scenario reflects the configuration of the radiocommunications systems to be simulated.

To create or update a simulation workspace, you need to follow the following steps:

1. Set the technical characterisitic of the various systems that you want to investigate. In the example of Figure 26 the first system is Generic and the second one is an OFDMA UL system. Do not forget to export your system to the library environment so that you can reuse your work next time.

2. Set the scenario (see section ‎10);
3. Set the path characteristics between the victim and the interferer (relative position, interferer’s density, path loss correlation and propagation model). You can also add, duplicate, etc... links;
4. In the simulation control panel you can both set the number of events to simulate and decide whether you want to run the simulation in the debug mode or not;
5. Having reviewed the scenario, you can run your simulation.
