“Performance of Large Scale Antennas for 5G Cellular Systems”

Abstract

The fifth generation of mobile wireless communication systems (5G) is a promising source for magnificent levels of connectivity and Quality of Services (QoS) to satisfy the growth of the number of users in a certain area and the growth of the data demanded. Massive Multiple Input Multiple Output (M-MIMO) technology is one of the key technologies that enables the 5G to satisfy its goals, such as enhancing the achievable data rate, minimizing the latency, enhancing the traffic capacity and improving the mobility. The collocated M-MIMO system is the system where the BS is mounted by a massive number of antennas (much larger than the number of active users). M-MIMO provides higher spectral and energy efficiency and reduces the inter-cell interference (ICI) to a certain level. However, the ICI remains a limiting factor in M-MIMO with its cellular distribution model.
