model.
b
Here the constants b 1 and b 2 for the dual slope fitting are 130 MHz and 16.4 MHz, respectively. In spite
of the fact that the best fit can be obtained with the dual slope profile we will use a single slope profile in
the model for simplicity. Then the line fitted to the profile will have the time-constant b = 60 MHz.
5.4.8 Number of ZDSC
This sub-section presents number of clusters that has been extracted from measurements. The extracted
clusters are based on definition that used in the channel model as clusters with zero delay spread. In other
words, the considered clustering is in angle domain. These clusters are called zero-delay-spread clusters
(ZDSC). Detailed discussion about ZDSC is given in Chapter 4.
5.4.8.1 Scenario A1
The distribution of the number of clusters was investigated in an A1 indoor environment. The results are
shown below as the 10, 50 and 90 % percentiles of the distribution.
Table 5.25: Percentiles for the number of paths in A1 indoor scenario and different propagation
conditions.

5.4.8.2 Scenario B1
Figure 5.50 shows the cumulative probability of the ZDSC in both LOS and NLOS conditions. Table 5.26
lists the 10, 50, 90 percentiles of the empirical cumulative probability of the extracted number of ZDSCs.
