Polynomial - and Quadratic -Approximation Algorithms for the Biased Traveling Salesman Problem in Bipartitioned Networks
Jingyang Zhao, Trung Q. Duong, Een-Kee Hong +1
The traveling salesman problem (TSP) is one of the fundamental problems in combinatorial optimization that asks for a minimum-cost Hamiltonian cycle in a complete undirected graph…
Statistical Analysis of Primary and Random Clusters in 318 GHz Terahertz Channels for Industrial IoT
Siyuan Shao, Peize Zhang, Pekka Kyösti +2
The ultra-high data rates enabled by terahertz (THz) communications pave the way for the demanding requirements of industrial Internet of Things (IIoT) applications, making the inv…
Cell-Level Channel Shaping for Rydberg Atomic Quantum Receivers in Satellite Uplinks With Doppler-Enabled Superheterodyne Reception
Qihao Peng, Qu Luo, Kezhi Wang +4
In this paper, we propose a self-superheterodyne Rydberg uniform array receiver for satellite uplink communications, in which the Doppler shift naturally induced by satellite motio…
