An architecture for hardware realization of the Gradient algorithm for sparse signal reconstruction is proposed. Gradient algorithm is recently proposed and generally belongs to convex optimization class of algorithms. It is an iterative algorithm where missing samples are reconstructed by using a procedure of gradient-based concentration improvement. The proposed scheme assumes that sparse domain...
In the era of technology expansion, the digital devices are made to achieve high resolution signal acquisition, producing a large amount of digital data. This is a common issue in sensing systems dealing with radar signals, multimedia signals, medical and biomedical data, etc. The acquisition process is done according to the Shanon-Nyquist theorem with the sampling rate which is usually at least twice...
