A Sparse CoSaMP Channel Estimation Algorithm With Adaptive Variable Step Size for an OFDM System
International Journal of Aerospace EngineeringCompressive sampling matching pursuit (CoSaMP), as a conventional algorithm requiring system sparsity and sensitive to step size, was improved in this paper by approximating the sparsity with adaptive variable step size. In the proposed algorithm (CoSaMP

Distributed Variable Sample-Size Stochastic Optimization With Fixed Step-Sizes
IEEE Transactions on Automatic Control, 2022 The paper considers distributed stochastic optimization over randomly switching networks, where agents collaboratively minimize the average of all agents' local expectation-valued convex cost functions. Due to the stochasticity in gradient observations, distributedness of local functions, and randomness of communication topologies, distributed ...
