IEEE International Symposium on Information Theory
作者: Alexander Barg Arya Mazumdar Department of ECE and Institute for Systems Research University of Maryland College Park USA Dobrushin Mathematical Laboratory Institute for Problems of Information Transmission Russian Academy of Science Moscow Russia
Codes for rank modulation have been recently proposed as a means of protecting flash memory devices from errors. We study basic coding theoretic problems for such codes, representing them as subsets of the set of perm... 详细信息

European Wireless Conference (EW)
作者: Barbara Staehle Dirk Staehle Rastin Pries Institute of Computer Science University of Würzburg Wurzburg Germany
The IEEE 802.11 standard supports a variety of modulation and coding schemes (MCSs). In 802.11-based wireless mesh networks (WMNs) it is hence possible to adapt the link rate to the channel conditions. In particular, ... 详细信息
