Performance Evaluation of MIMO in Urban Microcell for Dhaka City at 28 GHz Frequency

Abstract

5th generation cellular network is the upcoming revolution in the cellular communication world. It tends to operate in millimeter wave frequency to increase the usage for the next decade. While the researcher focuses on optimising spectral efficiency and increases bandwidth for incredible demand, only the mmWave spectrum have capability that can accommodate the ever-expanding consumption for the wireless network. The 28 GHz frequency band is a serious candidate for mmWave communication with more than 3 GHz of available bandwidth. The line of Sight (LOS) is a direct line between the radio transmitter and receiver and many types of radio transmissions depend on it. Unfortunately, for arbitrary transmission networks, obstacles are commonly caused by non-line-of-sight (NLOS) conditions. This thesis presents a proper number of selection antenna element in 28 GHz frequency in NLOS and LOS environment and their characteristics by analysis of different channel parameter in Urban microcell scenario for Dhaka city. This thesis also discusses the radio propagation mechanisms that impact the performance of the network in the form of time delays, received power, azimuth AoD, Elevation AoD, Azimuth AoA, Elevation AoA, path-lost and RMS delay in LOS and NLOS environments.
