Next, we examine the overall statistics of the channel gain. From Fig. 3.8a, it is shown that the PDFs exhibit multiple peaks for LOS links. When the UE is moving, it experiences different relative positions against the BSs in terms of orientation and distance, and thus the distribution of the channel gain is associated with the mobility pattern. As aforementioned, the users pass by some specific areas with higher probabilities; therefore, several peaks emerge in the PDF of the channel gain, which feature the regularity of the channel status at those frequently visited spots. For the PDFs shown in Fig. 3.8a, the channel gain distribution is fitted by parts of Nakagami distribution with respective weights. The overall PDF of multiple-peak Nakagami distribution in LOS links is given by where
