Due to the huge technology evolution nowadays, the world is moving towards implementing new advanced networks aimed to provide better services.5G will need to meet very challenging requirements and cover a wide range of scenarios and services. Utilizing unused mmWave spectrum is one key enabling solution for meeting the extreme data demand growth. While mmWave spectrum offers a great opportunity to increase capacity, little is known about the propagation channel characteristics. So in our project we will focus on studying 5G propagation channel. In the first part of the project, we started with studying two technologies of 5G. The first one is mmWave, which will provide a huge amount of unused spectrum to serve huge amount of users and to provide a huge data rate. Then we studied concept of MIMO system, Almouti code, Space Time Block Coding, and OSTBC, and QO-STBC. Then by using EVCM, we used Matlab to see effect of adding MIMO to signal based on different coding techniques. Then we studied Saleh-Valenzuela model for indoor environments. The last thing was taking real data from NYUSIM to study effect of Humidity, Rain rate, and changing number of transmitter and receiver antennas on Path Loss. For the second part of this project, we started our project with testing Flat fading channel and real channel for a MIMO system, based on coding technique and based on changing number of transmitted antennas. Our testing was on Matlab, where we use a code to implement MIMO system for a real and flat fading channel, and we attach the result we got. Then we moved to beamforming with its two architecture, analog and digital beamforming. We tested MIMO channel with beamforming, and saw how adding beamforming will enhance performance. Then, we saw how full duplex can be achieved using hybrid transformer connected to single pole balancing circuit, and it was tested on Matlab Simulink, and we attach the result that we got.
