Federated Learning with Erroneous Communication Links

no code implementations31 Jan 2022 Mahyar Shirvanimoghaddam, Ayoob Salari, Yifeng Gao, Aradhika Guha

We proved that the FL algorithm in the presence of communication errors, where the CN uses the past local update if the fresh one is not received from a device, converges to the same global parameter as that the FL algorithm converges to without any communication error.

Clustering-based Joint Channel Estimation and Signal Detection for Grant-free NOMA

no code implementations7 Oct 2020 Ayoob Salari, Mahyar Shirvanimoghaddam, Muhammad Basit Shahab, Reza Arablouei, Sarah Johnson

Since the accuracy of the utilized clustering algorithm depends on the number of the data points available at the receiver, the proposed technique delivers a tradeoff between the accuracy and block length.

New Density Evolution Approximation for LDPC and Multi-Edge Type LDPC Codes

2 code implementations16 May 2016 Sachini Jayasooriya, Mahyar Shirvanimoghaddam, Lawrence Ong, Gottfried Lechner, Sarah J. Johnson

We observe that the assumption of symmetric Gaussian distribution for the density-evolution messages is not accurate in the early decoding iterations, particularly at low rates and with punctured variable nodes.
