TL;DR
This paper analyzes uplink massive MIMO systems with many antennas at the base station, focusing on achievable degrees of freedom and power savings without requiring channel state information at the receiver.
Contribution
It provides a theoretical analysis of system performance metrics like degrees of freedom and power efficiency in large-scale MIMO without channel state information.
Findings
Achievable degrees of freedom increase with the number of antennas.
Significant power savings are possible as the number of receive antennas grows.
Performance improves even without channel state information at the receiver.
Abstract
We study the performance of uplink transmission in a large-scale (massive) MIMO system, where all the transmitters have single antennas and the receiver (base station) has a large number of antennas. Specifically, we analyze achievable degrees of freedom of the system without assuming channel state information at the receiver. Also, we quantify the amount of power saving that is possible with increasing number of receive antennas.
