Bandwidth-Efficient Synchronization for Fiber Optic Transmission: System Performance Measurements
Oluyemi Omomukuyo, Octavia A. Dobre, Ramachandran Venkatesan +1
In this article, we first provide a brief overview of optical transmission systems and some of their performance specifications. We then present a simple, robust, and bandwidth-eff…
Resource Allocation for Downlink NOMA Systems: Key Techniques and Open Issues
S. M. Riazul Islam, Ming Zeng, Octavia A. Dobre +1
This article presents advances in resource allocation (RA) for downlink non-orthogonal multiple access (NOMA) systems, focusing on user pairing (UP) and power allocation (PA) algor…
Ergodicity of the Spin-Boson Model for arbitrary coupling strength
Martin Koenenberg, Marco Merkli, Haifeng Song
We prove that the spin-boson system is ergodic, for arbitrary strengths of the coupling between the spin and the boson bath, provided the spin tunneling matrix element is small eno…
Convergent sequences of sparse graphs: A large deviations approach
Christian Borgs, Jennifer Chayes, David Gamarnik
In this paper we introduce a new notion of convergence of sparse graphs which we call Large Deviations or LD-convergence and which is based on the theory of large deviations. The n…
