In signal processing, extracting information from a signal often requires transforming it into another domain using a suitable representation. Current representations for period estimation include the Discrete Fourier Transform (DFT), the Ramanujan Periodic Transform (RPT), and the Orthogonal Comple…
In multi-hop multi-relay cooperative wireless communication systems, node selection for physical layer security (PLS) is an important problem. By defining secrecy capacity based on localized vertex spectrum (LVS), three optimization problems namely i) the best destination for a given eavesdropper, i…
Recovering a sparse target vector with reduced sparsity from a given observation vector is a major challenge in many applications. The well-known tail-minimization approaches tackle this challenge by minimizing the tail part of the target vector. Building upon this, recent development, the tail fast…
In practice, Analog-to-Digital Converter (ADC) is used to perform sampling. A practical bottleneck of ADC is its lower dynamic range, leading to loss of information. To address this issue, researchers suggested folding operation on the signal using a modulo operator before passing it as an input to…
