Spectral Efficiency Enhancement using Clustered LTV Channel Model in mmWave Doubly Massive MIMO System

Abstract

Telecommunication industry has many expectations from the 5G technology to enhance the telecommunication network. One major expectation is to entertain large number of users with very high data rate and the other is to deploy massive number of sensor to support several connections simultaneously. Transmitter and the receiver can be equipped with huge number of antennas due to the application of millimetre waves (mmWaves) in 5G cellular system. Ideally, a debit card can accommodate more than 160 antennas. This concept is known as doubly massive MIMO. At mmWaves, the physical propagation is characterised by a "clustered" channel model. In this paper, we build upon the previous work on clustered model and present the simulation results for linear time-variant (LTV) channel by incorporating the effects of mobility. Our work shows that the effect of mobility on the system performance is more prominent as compared to that of antennas.
