In this paper, we introduce a Deep Neural Network (DNN) to maximize the Proportional Fairness (PF) of the Spectral Efficiency (SE) of uplinks in Cell-Free (CF) massive Multiple-Input Multiple-Output (MIMO) systems. The problem of maximizing the PF of the SE is a nonconvex optimization problem in the design variables. We will develop a DNN which takes pilot sequences and largescale fading coefficients of the users as inputs and produces the outputs of optimal transmit powers. By consisting of…

On proportional fairness of uplink spectral efficiency in cell-free massive MIMO systems
Simulation results show that the SE PF maximization not only offers approximately the achievable sum rates as compared to the sum-rate maximization but also provides an improved trade-off between the user rate fairness and the achievablesum rate.
Sum Spectral Efficiency Maximization in Massive MIMO Systems: Benefits from Deep Learning
This paper proposes a new optimization algorithm, inspired by the weighted minimum mean square error approach, to obtain a stationary point in polynomial time, and uses this algorithm together with deep learning to train a convolutional neural network to perform the joint data and pilot power control in sub-millisecond runtime.
On the Total Energy Efficiency of Cell-Free Massive MIMO
This work considers the cell-free massive multiple-input multiple-output (MIMO) downlink, where a very large number of distributed multiple-antenna access points (APs) serve many single-ant antenna users in the same time-frequency resource, and derives a closed-form expression for the spectral efficiency taking into account the effects of channel estimation errors and power control.

Cell-Free Massive MIMO Versus Small Cells
Under uncorrelated shadow fading conditions, the cell-free scheme provides nearly fivefold improvement in 95%-likely per-user throughput over the small-cell scheme, and tenfold improvement when shadow fading is correlated.
Solution of the multiuser downlink beamforming problem with individual SINR constraints
The optimality and global convergence of the algorithm is proven and stopping criteria are given, and the global optimum of the downlink beamforming problem is equivalently obtained from solving a dual uplink problem, which has an easier-to-handle analytical structure.
