Novel opportunistic cooperative multicast scheme for NOMA by Yin LU, Jirong CHEN, Haowei BIAN, Hongbo ZHU

“…The cognitive radio technology was applied to non-orthogonal multiple access (NOMA) cooperative multicast system,the feasibility of using users as relays was studied,and a two-level cooperative transmission scheme with parameterized multicast candidate sets was proposed.Specifically,the scheme first selected the candidate set according to the cardinality q,and then selected the best forwarding node based on the channel gain between the primary users and the candidate secondary users.Simulation results show that,through the reasonable selection of the cardinality q,the proposed scheme can greatly reduce the diversity gain of the secondary users while simultaneously increasing the diversity gain of the primary users.In NOMA cooperative multicast scenario composed of N multicast users,the proposed scheme can increase the diversity gain of the primary users from 2 to min(N-q+2,q+1) to meet their reliability requirements.…”

Moments, Exponential Sums, and Monodromy Groups by Nicholas M. Katz, Pham Huu Tiep

“…As a byproduct, we determine the number of irreducible components of maximal dimension in certain intersections of Fermat surfaces. We also show that in any family of such local systems, say parameterized by an affine space S, there is a dense open set of S over which the geometric monodromy group of the corresponding local system is a fixed known group.…”

SPECTER: efficient evaluation of the spectral EMD by Rikab Gambhir, Andrew J. Larkoski, Jesse Thaler

“…In this work, we obtain a closed-form expression for the Riemannian-like p = 2 SEMD metric between events, eliminating the need to numerically solve an optimal transport problem. Additionally, we show how the SEMD can be used to define event and jet shape observables by minimizing the distance between events and parameterized energy flows (similar to the EMD), and we obtain closed-form expressions for several of these observables. …”
