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 ...

Single-carrier transmission scheme for extracting characteristic parameters of 32-Point 6PolSK-QPSK

EURASIP Journal on Advances in Signal Processing, 2022
Six polarization-shift keying quadrature phase shift keying (6PolSK-QPSK) signal modulation format is formed by different representations of QPSK. A variety of satisfactory single-carrier transmission schemes have been implemented in 24-Point 6PolSK-QPSK.
