10.3.1 Relative positioning of interfering link (Generic system)
The relative position of the Victim Receiver (VLR) and the Interfering Transmitter (ILT) depends on the various options presented below. There is a unique simulation radius (Rsimu) contrary to the 2 coverage radius (one for the victim and one for the interfere...
10.3.2 Relative positioning of interfering link (Cellular system)
The relative position of the Victim Receiver (VLR) and the Interfering cellular system depends on the various options presented below. Figure 228: Relative positioning of a cellular interfering link with a generic victim system Cor. (interfering...
10.3.3 Interferers density
The panel is activated if "Uniform density" or/and "closest interferer" mode is selected. See Annex A13.2.2 for more details on the calculation. Figure 230: Interferers density panel (only in "Uniform density" and "closest interferer” mode) Table 47: Settin...
10.3.4 Pathloss correlation
The panel is activated if the victim is either OFDMA UL or OFDMA DL. It is decribed in more details in Section 9.11.
10.3.5 Propagation Model
You can choose the suitable propagation model to be applied when calculating signal loss between the ILT and the VLR. A choice and settings of propagation models are presented in ANNEX 17:.
10.4.1 Spectrum sensing characteristics
When the spectrum sensing is activated, the tab “Interfering link transmitter to victim link transmitter path” will become editable (#1 of Figure 231) and you can set the input parameters of the CR algorithm (#2). Note that the frequency of the interferer is d...
10.4.2 Detection of threshold
In relation to the spectrum sensing results, if this CR detect that a victim system is in the vicinity it will select an appropriate operating frequency and it will lower its emission based on an e.i.r.p. max in block limit defined in the spectrum sensing char...
10.4.3 Probability of failure
This feature is input selectable (by default, it is de-activated).The probability of failure may account for the failure in selecting wrongly a non_available channel for one event. This means that when a failure appears, a channel which was initially selected ...
10.4.4 Adjacent channel scenario - e.i.r.p. max. in-block limit
In the case where the WSDs are not allowed to transmit in the same operating frequency as for the victim DTT device, the WSDs can decide to transmit in the adjacent bands or channels. This scenario is illustrated in Figure 234 In this example the WSDs have sen...
10.4.5 Propagation Model
You can choose the suitable propagation model to be applied when calculating signal loss along the transmitter and the receiver path. A choice and settings of propagation models are presented in ANNEX 17:.
11.1 Event processing concept
The Event Processing tab is the place in SEAMCAT where you can set the Event Processing Plugin (EPP). The EPP is a plugin that is given access to the EventResults, one by one, as they are produced by the simulation - an EPP can be viewed as an adjacent simulat...
11.2 Event processing GUI
The Event processing GUI consists of 2 main parts as shown in Figure 238. On the left hand side you can add ( ) or duplicate ( ) an EPP to the simulation, duplicate an EPP, remove ( ) an EPP from the simulation and export ( ) an EPP. There exist some pre...
11.3 Loading an EPP to a simulation
To use EPP in a simulation go to the event processing tab and click the plus sign (Figure 239). Figure 239: Using EPP in a workspace You will be prompted with a list of available EPPs and their preview as shown in Figure 240. Figure 240: Lis...
11.4 Configuring an EPP
The EPP can be configured as wanted for this particular simulations soon as it is loaded to the simulation workspace. In this example the EPP called “Demo 1: Collect intermediary results” is loaded. With this EPP, you can select the intermediary vector results...
Member administration
As a Chair in a group, you are also co-responsible to maintain the memberlist in the chat. This includes: Inviting users Removing users Approve/Reject user access You are therefor appointed "admin" rights in the chat groups you are responsible for. In the Si...
12.1.1 Simulation Summary
The simulation summary (left of Figure 242) provides a quick access to the mean, median and standard deviation of the dRSS, iRSS unwanted and iRSSblocking The mean is computed using the simulated results in dB. The median is computed using the simulated result...
12.1.2 Simulation status
The progress bar (right of Figure 242) reflects the percentage of events simulated with respect to overall number of events specified in the simulation control window in the scenario tab. Figure 242: Simulation status
12.1.3 Generic system outline
During the event generation all involved transceivers (ILT, ILR, VLR and VLT) are plotted in graphical display window placed on the simulation outline tab. Figure 243: Example of “Scenario outline” for a generic system 1 vs generic system 2 type of simulati...
