Codebook Based Multi-User MIMO for 5G

Sammanfattning: Better signal strength is required to provide a good signal service to the UE. For this, different methods and techniques are available, one of them is codebook type II precoding. This method has a potential to provide an amount of energy to the user in the required direction more precisely than Codebook type I. Therefore this method will be put to the test, for a given SNR range, by comparing the quality of the beamformed signal to non-beamformed signal. Additional studies have been made about the different characteristics of the channel with simple changes in the base station with a different antenna configuration exploiting MIMO case. This will lead to have a large array gain and also spectral efficiency is increased in spatial domain. All these characteristics are applied for multi-layers and multi-users. For a better understanding of the topic and for proof of concept, it is being restricted to a single user and a single layer.
