Complex Coprime Frequency Sum Based Signal Representation for Period Estimation

Shaik Basheeruddin Shah, Nazar T. Ali, Ahmed Altunaiji, Vijay Kumar Chakka, Mohamed I. AlHajri

ICASSP 2025accepted

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…

Node Selection for Physical Layer Security Using Graph-Based Vertex-Frequency Representation

Venugopalachary Kotha, Vijay Kumar Chakka, Shaik Basheeruddin Shah, Nazar T. Ali

ICASSP 2025accepted

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…
