IEEE Conference on Vehicular Technology (VTC)
作者: Qiuliang Xie Kewu Peng Jian Song Zhixing Yang Tsinghua National Laboratory of Information Science and Technology (TNList) Department of Electronic Engineering Tsinghua University Beijing China
Bit-interleaved coded modulation (BICM) is a sub- optimal scheme from the average mutual information (AMI) point of view due to independent demapping. However, this AMI loss can be neglected for signal constellations ... 详细信息

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference
作者: Trung Thanh Nguyen Lutz Lampe Department of Electrical and Computer Engineering University of British Columbia Vancouver Canada
We propose a novel communication scheme that combines rateless transmission and multilevel coding (MLC). The scheme is able to attain a throughput that is equal to the constellation-constrained channel capacity. It is... 详细信息

International Teletraffic Congress, ITC 21
作者: Barbara Staehle Dirk Staehle Rastin Pries Institute of Computer Science University of Würzburg Wurzburg Germany
Wireless mesh networks (WMNs) support a variety of modulation and coding schemes (MCSs) and hence enable adaptive modulation and coding. On the one hand, adaptive modulation and coding significantly increases the over... 详细信息

International Symposium on Wireless Communication Systems (ISWCS)
作者: Muammar A. Alfasi Yousef R. Shayan Department of Electrical and Computer Engineering Concordia University Montreal Canada
As shown in the literature, the performance of bit-interleaved coded modulation systems (BICM-ID) depends on the binary sequences mapping to constellation symbols. In this paper, we present a new multidimensional mapp... 详细信息
