In this case, the Blocking is provided in dB and represents the attenuation of the receiver at a given frequency offset (see A8.7). The resulting receiver attenuation equals the user-defined input values. Then, the iRSSblocking at the interferer operating freq...

In this calculation mode the function blockMax Interf Signal (Df) that you entered represents the absolute power level (in dBm) of maximum interfering signal (maximum acceptable interfering power), which might be tolerated by the receiver at a given frequency ...

This mode is identical to the “sensitivity” mode since the only difference is that the Blocking value (relative to the noise floor) is provided in dB. The software processes the information using exactly the same method to obtain the value of the receiver atte...

The following graphics presents the input parameters to activate when the intermodulation mechanism is to be investigated. The intermodulation rejection mask is expressed in dB versus frequency offset (MHz). Results details can be found in Section 12.3.3. ...

The following graphics presents the input parameters to activate when the overloading mechanism is to be simulated. Figure 107: Activation of the overloading feature in SEAMCAT     The overloading mask is expressed in power (dBm) versus frequency of...

In this section the Free Space Model is used to derive the attenuation on the different paths and the Victim Link and Interfering Link operate at the same frequency – 1000 MHz – co-channel interference. Figure 115 presents an illustration of the various radii ...

The distance between the Victim link receiver and the Interfering link transmitter is referred to as the simulation radius (see ANNEX 13:). It can be defined as shown in Figure 117. Figure 117: Definition of the minimum distance   Using this feature...

The number of active transmitters that will be uniformly located within the simulation radius is given by:                                                                                               (Eq. 28)   Figure 120 presents the GUI with the input valu...

When you select the “None” mode (see ANNEX 13:), he can also define a Uniform density of terminal/transmitter by using the Uniform polar distance defined within the path distance factor and a uniform distributed path azimuth (0 to 360 deg).Uniform polar distan...

If a minimum protection distance  between the victim link receiver and interfering link transmitter is introduced then the simulation radius may then be calculated by using the following formula:                                                                 ...

Note: The power control is used only in this section. When considering other sections, the power control feature should be deactivated. A power control feature is implemented within SEAMCAT. When this feature is activated it introduces a variation of the inter...

For simplification, we consider that the Victim link receiver and the Interfering link transmitter are defined using the following assumptions (again 1 km distance between the Interfering link transmitter and the Victim link receiver). The iRSSunwanted is then...

This tab allows you to update all scenario parameters of for a generic system . In the upper part of the tab, you have three panels.   Figure 142: Generic system  

You can name and write some description of the victim system you want to simulate. 

The user can enter the frequency. The frequency value is overwritten at the “Scenario” tab level.   Table 8: Generic system – General panel Description Symbol Type Unit Comments Frequency f Distribution or Scalar MHz Distribution o...

It can be the VLR or the ILR as illustrated in Figure 143.   Figure 143: Receiver illustration as VLR or ILR   The receiver consists of 5 panels (Figure 144); Receiver identification, antenna pointing, antenna patterns identification, reception cha...

This panel is a common interface that is reused in all other radio system.   Table 9: Receiver identification Description Symbol Type Unit Comments Library   - Library - Allows to import/export the receiver characteristics from/to th...

This panel is a common interface that is reused in other radio system. It contains all information relative to the antenna other than the radiation pattern.   Table 10: Receiver antenna pointing GUI Description Symbol Type Unit Comments Anten...
