System Plugin (SP)

System Plugin (SP) • System Plugin (SP): A plugin that contains the complete implementation of a radio system (transmitter, receiver and all their associated parameters)

SP Exercise • Sample System Plugin: In this exercise we will implement a System Plugin. Because the System Plugins are very complex, this exercise contains much more code than the other exercises. In this exercise, we will only add a few pieces. • The exercise contains the definition of a simple SP. There is not much configuration possible – only the minimal amount to make it operate within the context of the ISE. • The aim of this exercise is to position one transmitter and one receiver during the simulation steps “victim setup” and “interfering setup” of the ISE.

SP Exercise • This project can be opened in Intelli. J IDEA Community Edition. • To start the exercise you need to access the file Sample. SPSimulation. java (under the src folder) in Intelli. J.

SP Exercise • Unzip the file Exercise 3_SP. zip and import it as a project into intelli. J. • Set it up as described in the Computer Setup presentation • Open the Sample. SPSimulation. java file:

SP: Implement the class Sample. SPSimulation. java • Implement the class Sample. SPSimulation. java. • Overview of the class:

SP: Implement the class Sample. SPSimulation. java • Implement the class Sample. SPSimulation. java. • Fill out the code following the comments in Steps 1 and 2. Step 1: Generate the positions of Tx and Rx for the Victim System: - The TX has a position of (0, 0). - The Rx is randomly positioned (x, y) with x and y varying between 0 and 1.

SP: Implement the class Sample. SPSimulation. java • Step 2: Generate the position for Tx and Rx for the Interfering System: – The Tx should have the position given by the position argument – The Rx is randomly positioned (x, y) with x and y varying between 0 and 1

SP: Build the. jar file • As described in the Computer setup presentation: – Build the. jar file : press Build -> Build Artifacts. . . -> Exercise 3. jar -> Build – The generated artifact is available under the folder out -> artifacts -> Exercise 3_jar

SP: Install the. jar file in SEAMCAT • Open the new SP from the Systems library in SEAMCAT. The plugin named Sample. SP should appear:

SP: Run the plugin • Create a new workspace and add the new SP by clicking on the library:

SP: Run the plugin • The new SP will appear in the System list:

SP: Run the plugin • Create an scenario using this SP as Victim and Interferer:

SP: Run the plugin • Set the correlation mode to “Correlated” • Set delta X and delta Y to -1

SP: Run the plugin • Run the simulation with 20. 000 events. • The simulation should complete fast and the resulting outline should look similar to this

SP: Run the plugin • The scenario outline look like two squares because we chose to place the VLT at (0, 0) (blue dot). • All the yellow dots (VLR) are placed randomly with x and y in the range [0, 1] (yellow squares). • For the interfering system we used a constant correlation delta of (-1, -1) so this repeats the pattern of the victim system but shifted by (-1, -1).

SP: Run the plugin • The event results panel shows the details of the last event:

SP: Run the plugin • We see the two systems surrounded by a circle defined by the method get. System. Coverage() , which is defined in the class Sample. SP. java. • This method returns square root 2 as the max length of any tx → rx link, which will be the case when the rx get the position (1, 1).
