A Sparse CoSaMP Channel Estimation Algorithm With Adaptive Variable Step Size for an OFDM System
Compressive 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 with variable step size abbreviated as Vss-Co...
