12.1.4 Cellular system outline
Once SEAMCAT has determined the number of UEs per cell either through simulation of optimal capacity (see Figure 197 for UL and Figure 198 for DL or by a value that you specify the actual simulation of snapshots begins. As with all scenarios this causes SEAMCA...
12.2 Overview of output results
Table 51: Interference criteria summary for various victim systems Victim system Intereference criteria Generic module (i.e. non CDMA/OFDMA) Probability of interference based on C/I, C/(I+N), (N+I)/N, I/N CDMA Capacity loss (i.e. number o...
Introduction
After running a simulation with generic system, each of these signals is displayed with indicated array size (i.e. the number of valid generated events), unit and then the type (vector, double etc..). Double-clicking on one of the vectors, the signal dialog wi...
12.3.1 Generated signals results
dRSS folder (ANNEX 4:) with dRSS vector; iRSS unwanted folder (ANNEX 5:) with as many iRSSunwanted vector for each interfering link and one vector for the sum; iRSS blocking folder (ANNEX 5:) with as many iRSSblocking vector for each interfering link ...
12.3.2 Calculated radius
The calculated radius folder contains the values of the coverage and/or simulation radii calculated for the event generation when set to non-correlated (See ANNEX 13:).
12.3.3 Intermodulation results
iRSS intermodulation folder (Figure 248) with as many iRSSintermod vector for each combinatory couple in case there are more than one interfering link and one vector for the sum. Figure 248: Intermodulation results folder
12.3.4 Overloading results
As a result of the equation described in Annex A5.4, for each event and at each frequency, the sum of the iRSSoverloading (iRSSsum_overloading) will be compared to the overloading treshold Oth(fi) at that frequency (fi). The difference, delta (in dB), will be ...
Introduction
When the cognitive radio mode is activated, SEAMCAT resturns the output vector shown in Figure 251 and described in Table 52. Figure 251: Output vector for the CR Table 52: Output results for CR simulation # Item Description 1 ...
12.4.1 sRSS vector
The sRSS vector (dBm) is merely the sRSS value calculated at the selected WSD frequency (i.e. where the WSD is allowed to transmit) for each of the event. Figure 252 displays the vector for each WSD. You can select any or all of the WSD (#1). The same applies ...
12.4.2 WSD frequency
This vector represents the actual selected frequency (MHz) at which the WSDs are allowed to transmit as the result of the spectrum sensing algorithm. (a) (b) Figure 254: Frequencies where the WSD...
12.4.3 WSD e.i.r.p.
The actual selected e.i.r.p. (dBm) at which the WSDs are allowed to transmit as the result of the spectrum sensing algorithm. This vector displays the e.i.r.p. for each of the WSD for all the events. In the example presented in Figure 256, the WSDs are transmi...
12.4.4 Victim frequency vector
The victim frequency vector (MHz) represents the frequency at which the victim device transmits per event.
12.4.5 Average e.i.r.p. per frequency
It presents the average e.i.r.p. per event (dBm vs MHz) for all the active WSDs transmitting at a certain frequency such that: (Eq. 68) Let us assume a different example from above, where 4 channels have been identified for the WSD to operate. Figure 2...
12.4.6 Average active WSDs per frequency vector
It provides the average number of active WSD per event for a specific frequency: (Eq. 69) Re-using the example of Figure 257, Figure 258 indicates that, with for instance 5 WSDs set as input parameters, an average of...
12.5.1 CDMA capacity finding
During the pre-simulation part, the system estimates the load of the network as shown in Figure 259. The results are presented as in Figure 260. Figure 259: Example of the CDMA UL capacity finding status Figure 260: Pre-simulated results (...
12.5.2 CDMA results
Once SEAMCAT has completed the simulation, the results are shown as displayed in Figure 261, when the CDMA network is the victim. This figure presents the difference between the 2 steps power balancing process (1-initial power balancing, 2- power balancing aft...
12.5.3 CDMA results for cell selection algorithm
When the CDMA “cell selection” algorithm is simulated, the following output vectors are also available for scrutiny: Average network noise rise (initial without external interference): value at step 1 (i.e. before the algorithm - see Annex A15.3.2)...
12.6 OFDMA output results
The results of the OFDMA simulation are given in terms throughput loss of the OFDMA victim. Figure 263 presents an overview of the simulation results. It consists of the achieved bitrate (with or without external interference) for the reference cell or the who...
