Precoding-oriented Massive MIMO CSI Feedback Design

no code implementations22 Feb 2023 Fabrizio Carpi, Sivarama Venkatesan, Jinfeng Du, Harish Viswanathan, Siddharth Garg, Elza Erkip

Downlink massive multiple-input multiple-output (MIMO) precoding algorithms in frequency division duplexing (FDD) systems rely on accurate channel state information (CSI) feedback from users.

Learned Belief-Propagation Decoding with Simple Scaling and SNR Adaptation

no code implementations24 Jan 2019 Mengke Lian, Fabrizio Carpi, Christian Häger, Henry D. Pfister

As an example, for the (32, 16) Reed-Muller code with a highly redundant parity-check matrix, training a PAN with soft-BER loss gives near-maximum-likelihood performance assuming simple scaling with only three parameters.
