Biorthogonal Fourier transform for multichirp-rate signal detection over dispersive wireless channel

EURASIP Journal on Wireless Communications and Networking, 2018
Biorthogonal Fourier transform (BFT), consistent with the matched signal transform (MST), has been introduced to demodulate the M-ray chirp-rate signal which possesses good orthogonality in the BFT domain.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Wireless Communication Graphs

Proceedings of the 2004 Intelligent Sensors, Sensor Networks and Information Processing Conference, 2004., 2005
We consider graph models which represent communication in wireless ad-hoc networks. In such networks, each node equipped with a radio has a certain transmission range, and all surrounding nodes in this range can receive a transmission. In ideal settings, this transmission range creates a circular disk around each node, so that disk intersection graphs ...
