Datasets associated with the article "Learning-Based Downlink Power Allocation in Cell-Free Massive MIMO Systems" published in IEEE Transactions on Wireless Communications

The datasets are associated with the non-orthogonal pilot assignment case in the article. The input and labelled output for training the models therein, and the computed SE performance for the conventional optimization approaches are provided.

A brief description of the datasets:

• 'APpositions.npy': Represents the access point (AP) 2D locations utilized to generate the datasets.
• 'dataset_betas.npy': Large-scale fading coefficients in linear scale [W]. Represents the input to the DNN models.
• 'dataset_mu_XX_WMMSE_ADMM.npy': Locally optimal square roots of power coefficients [sqrt(W)] for the sum-SE maximization objective with; (1) XX = MR, and (2) XX = RZF precoding schemes. Represents the labelled output of the DNN models.
• 'dataset_mu_XX_WMMSE_PF_ADMM.npy': Locally optimal square roots of power coefficients [sqrt(W)] for the proportional fairness (PF) maximization objective with; (1) XX = MR, and (2) XX = RZF precoding schemes. Represents the labelled output of the DNN models.
• 'dataset_SE_XX_WMMSE_ADMM.npy': Per user spectral efficiency (SE) in [bits/s/Hz] for the sum-SE maximization objective with ; (1) XX = MR, and (2) XX = RZF precoding schemes.
• 'dataset_SE_XX_WMMSE_PF_ADMM.npy': Per user spectral efficiency (SE) in [bits/s/Hz] for the proportional fairness (PF) maximization objective with ; (1) XX = MR, and (2) XX = RZF precoding schemes.
