2. Getting around in SEAMCAT

A sanity check on the suitability of a propagation model can be done by clicking on <Tools/Test Propagation Models> in the main menu of SEAMCAT, by clicking on the icon () of the toolbar or by pressing <CTRL+SHIFT+M>. With this feature, it is possible to evalu...

2.17 Testing distribution functions

2. Getting around in SEAMCAT

A sanity check on distributions can be done with the test distribution function from the menu bar of SEAMCAT. The result of generating random values using a particular distribution type can be tested by selecting the <Test Distributions> command from the Works...

2.18 Testing unwanted emissions function

2. Getting around in SEAMCAT

A sanity check on the unwanted emission calculation can be done by using the <Test Rel. Unwanted> emission function in the menu bar of SEAMCAT, by clicking on the icon of the toolbar ( ) or by pressing <CTRL+SHIFT+U>. The definition of unwanted emissions mask...

2.19 Multiple vectors comparison

2. Getting around in SEAMCAT

All the vectors (or a subset) that have been generated for one workspace or more can be seen at once. For this, the <Compare Vectors> command is available by clicking this icon  or by pressing <CTRL+SHIFT+V> to open the dialog box in Figure 57.   It allows d...

2.20 Pocket calculator

2. Getting around in SEAMCAT

SEAMCAT contains a builtin pocket calculator. Select the command < Tool/Pocket Calculator> from the Workspace menu, click on the pocket calculator icon of the toolbar ( ) or CTRL+SHIFT+C to activate the Pocket calculator window:    Figure 58: SEAMCAT pocket ...

2.21 Online manual and help content

2. Getting around in SEAMCAT

SEAMCAT provides a direct access to the online manual by clicking on the following symbol .  Each panel contains a specific link where detailed information on the feature or algorithm can be found. In case of need for further information, clarification, or in ...

2.22 Report enhancements and bugs

2. Getting around in SEAMCAT

The SEAMCAT tool is thoroughly tested but in case of need to report bugs or enhancements, send an email to seamcat@eco.cept.org by describing the issue and attach relevant files (i.e. workspace files, screen shots, system log file etc…). Further information on...

2.23 Installing plugins in SEAMCAT

2. Getting around in SEAMCAT

From the SEAMCAT library menu it is possible to install a library as a .jar file. By creating a new .jar entry and adding the file SEAMCAT will now include this plugin to be selectable when configuring scenarios.  Figure 61: Installing plugins After installat...

2.24 Pausing and RESUMING a simulation

2. Getting around in SEAMCAT

A simulation can be paused when clicking on the Pause button in the simulation control part of the Scenario tab ( ). The simulation pauses and all other commands/buttons are, meanwhile, disabled except the stop button (  ). The simulation is resumed by clicki...

Methods for applying time-domain activity of transmissions in SEAMCAT simulation

2. Getting around in SEAMCAT 2.25 Considering time domain Tx activity

Tx power Distribution Applicability: cellular or generic systems with multiple interferers where individual transmitters exhibit independent random time domain behaviour (e.g. mobile networks, SRDs) The user can set User defined (Stair) distribution wh...

3.1 Setting the scenario

3 Example of running a simulation

  Running a simulation consists essentially in setting the input parameters of the victim and the interfering system according to your requirement. Similarly, you need to consider the requirement of the geographical location of the various systems. For this e...

3.2.1 Victim link

3 Example of running a simulation 3.2 Calculating the dRSS

The victim parameter characteristics summarised in Table 6 should be entered into SEAMCAT.   Table 6: Characteristics of the victim link pair of receiver and transmitter Parameters Value Units Operating Frequency 1000 MHz Transmitter pow...

3.2.2 System to be a victim

3 Example of running a simulation 3.2 Calculating the dRSS

In order to set up a workspace, the first step is to set the system that will be used as victim: set the characteristics of the receiver  (that will be the victim link receiver (VLR)) and the transmitter (that will be the victim link transmitter (VLT)). System...

3.2.4 Transmitter

3 Example of running a simulation 3.2 Calculating the dRSS

Set now the victim link transmitter by selecting the transmitter tab Figure 74: Selecting the transmitter tab The parameters should be filled as follows: The power is 30 dBm; (#1 of Figure 75) An omni-directional antenna of 9 dBi is used; The antenna he...

3.2.5 Positioning the VLT vs VLR

3 Example of running a simulation 3.2 Calculating the dRSS

Define now the positions of transmitters and receivers of the victim link. Figure 76: Selecting the Tx to Rx path tab   SEAMCAT allows defining the locations of the Victim link receiver and the Victim link transmitter in a fixed manner (correlated) or followi...

3.2.6 Selecting the propagation model

3 Example of running a simulation 3.2 Calculating the dRSS

Since both the transmitter and the receiver characteristics and the location between the two have been defined, the propagation model needed for the simulation can be now selected. To simplify this task, let us assume that the free space model is used to calcu...

3.2.7 Calculating the dRSS by hand

3 Example of running a simulation 3.2 Calculating the dRSS

Using the Free space equation, the power received by the Victim link receiver (dRSS) can be easily derived:   (Eq. 17)   Keep this calculation in mind, as it will be compared with what SEAMCAT calculates in the following sections.

3.2.8 Export/import your system to library

3 Example of running a simulation 3.2 Calculating the dRSS
