5G millimeter wave channel model of tropical coasts of Iran (A case study of Chabahar)

Millimeter wave channel modeling of the fifth generation (5G) cellular networks is very important in every region because of different weather parameters, especially the tropical coasts of Iran (humid climate) are very effective in the millimeter wave channel model. According to the economic importance of the Chabahar region and the development of its telecommunication networks, and also because of the extreme humidity of the region, in this article, the 5G millimeter wave channel model has been investigated in the frequency bands of 28, 38, 60, and 73 GHz. In the channel modeling the NYUSIM simulator has been used as a tool to generate parameters received power of the channel, path loss exponent (PLE), and root mean square (RMS) delay spread for omnidirectional and directional power delay profile (PDP). The selected scenario is the urban microcell with line-of-sight (LOS) and non-line-of-sight (NLOS) propagation environments and considering two types of X-Pol and Co-Pol polarization for the antenna. The results show that the received power of the channel and PLE depend on the type of polarization and propagation environment, and RMS Delay Spread depends on the type of propagation environment. NLOS environment and X-Pol polarization reduce the received power of the channel and increase the PLE. Also, the RMS delay spread decreases in the NLOS environment.
