Energy-Efficient Uplink Power Allocation in Multi-Cell MU-Massive-MIMO Systems

In this paper, we investigate a joint uplink pilot and data power allocation strategy for energy-efficient communications under pilot contamination in multi-cell multi-user massive multiple-input multiple-output (MU-Massive-MIMO) systems. Assuming the maximum-ratio combining detection and a large number of antennas at the base station, the system energy efficiency (EE) is maximized over the ind...

Composite Channel Estimation in Massive MIMO Systems

We consider a multiuser (MU) multiple-input multiple-output (MIMO) time-division duplexing (TDD) system in which the base station (BS) is equipped with a large number of antennas for communicating with single-antenna mobile users. In such a system the BS has to estimate the channel state information (CSI) that includes large-scale fading coefficients (LSFCs) and small-scale fading coefficients ...

Information Rate Performance of Massive MU-MIMO Uplink with Constant Envelope Pilot-based Frequency Synchronization

In this paper, we consider a constant envelope (CE) pilot-based low-complexity technique for frequency synchronization in multi-user massive MIMO systems. Study of the complexity-performance trade-off shows that this CE-pilot-based technique provides better MSE performance when compared to existing low-complexity high-PAPR pilot-based CFO (carrier frequency offset) estimator. Numerical study of...

A Graph Theoretic Approach for Training Overhead Reduction in FDD Massive MIMO Systems

The overheads associated with feedback-based channel acquisition can greatly compromise the achievable rates of FDD based massive MIMO systems. Indeed, downlink (DL) training and uplink (UL) feedback overheads scale linearly with the number of base station (BS) antennas, in sharp contrast to TDDbased massive MIMO, where a single UL pilot trains the whole BS array. In this work, we propose a gra...

Uplink Interference Management in Massive MIMO Enabled Heterogeneous Cellular Networks

Considering the fact that massive multiple input multiple output (MIMO) macrocells and large number of small cells are deployed in the heterogeneous cellular networks for 5G, more users will be supported for uplink transmissions, which in turn brings more severe uplink interference. As a result, interference management is crucial for enhancing the uplink performance in these networks. In this l...
