Finite-Length Analysis of Frameless ALOHA with Multi-User Detection
Francisco Lazaro, Cedomir Stefanovic
In this paper we present a finite-length analysis of frameless ALOHA for a k multi-user detection scenario, i.e., assuming the receiver can resolve collisions of size k or smaller.…
Relative generalized matrix weights of matrix codes for universal security on wire-tap networks
Umberto Martínez-Peñas, Ryutaroh Matsumoto
Universal security over a network with linear network coding has been intensively studied. However, previous linear codes and code pairs used for this purpose were linear over a la…
Wirelessly Powered Communication Networks with Short Packets
Talha Ahmed Khan, Robert W. Heath, Petar Popovski
Wirelessly powered communications will entail short packets due to naturally small payloads, low-latency requirements and/or insufficient energy resources to support longer transmi…
