IEEE Photonics Conference (IPC)
作者: Murat Arabaci Ivan B. Djordjevic Ross Saunders Roberto M. Marcoccia Department of Electrical and Computer Engineering University of Arizona Tucson Tucson AZ USA Opnext Inc. Los Gatos CA USA
For optical transmission at 100 Gb/s and beyond, we propose using coded modulation based on non-binary quasi-cyclic LDPC codes. We show that the proposed schemes offer better performance than their counterparts based ... 详细信息

IEEE Workshop on Signal Processing Advances in Wireless Communications (SPAWC)
作者: Helka-Liina Maattanen Olav Tirkkonen Timo Roman Helsinki University of Technology Finland Nokia Research Center Finland Nokia Devices Research and Development Finland
In this paper we reduce the feedback overhead in two-stream MIMO with per stream link adaptation and codebook based precoding. The amount of feedback may be reduced by indicating the CQI of one stream in a differentia... 详细信息

International Conference on Wireless Communications and Signal Processing (WCSP)
作者: Hanghang Qi David Malone Vijay Subramanian Hamilton Institute National University of Ireland Ireland
Irregular LDPC codes can have capacity-approaching performance with an iterative BP decoder under AWGN channel with BPSK modulation. Generally in BPSK modulation, every bit within the block has the same power. In this... 详细信息

IEEE Conference on Vehicular Technology (VTC)
作者: Dan Zhao Axel Dauch Tad Matsumoto Japan Advanced Institute of Science and Technology Japan Information Technology University of Ulm (EBS) Germany Center of Wireless Communication University of Oulu Finland
Performances of BICM-ID systems strongly depend on the matching between mapping rule and code structure. This paper proposes a combined use of extended mapping (EM) and simple repetition code. Even with such a simple ... 详细信息

IEEE (first ITW conference of the year) Information Theory Workshop (ITW)
作者: Frédérique Oggier Patrick Solé Division of Mathematical Sciences School of Physical and Mathematical Sciences Nanyang Technological University Singapore CNRS LTCI Department Comelec TELECOM ParisTech Paris France
We address the problem of designing coset codes for use over slow block fading MIMO channels. We consider as inner code different codes built over cyclic algebras (in particular for different number of antennas), and ... 详细信息

IEEE International Symposium on Information Theory
作者: J. Harshan B. Sundar Rajan Department of ECE Indian Institute of science Bangalore India
Constellation constrained (CC) capacity regions of a two-user Gaussian multiple access channel (GMAC) have been recently reported. For such a channel, code pairs based on trellis coded modulation are proposed in this ... 详细信息

IEEE International Conference on Communications (ICC)
作者: H. Z. B. Chen R. Schober W. H. Gerstacker University of British Columbia Vancouver Canada University of Erlangen Nuremberg Germany
In this paper, we introduce robust cyclic space- frequency (CSF) filtering for systems combining bit-interleaved coded modulation (BICM) and orthogonal frequency division multiplexing (OFDM). The proposed robust CSF f... 详细信息

International Workshop on Signal Design and Its Applications in Communications (IWSDA)
作者: Jincheng Huang Shinya Matsufuji Takahiro Matsumoto Noriyoshi Kuroyanagi Pingzhi Fan Yamaguchi University Ube Yamaguchi Japan Chubu University Kasugai Aichi Japan Key Laboratory of Information Coding & Transmission Institute of Mobile Communications Southwest Jiaotong University Chengdu Sichuan China
Quasi-synchronous CDMA systems, which can remove co-channel interference by means of synchronization control and use of a ZCZ code, are useful for Short-Range Wireless communications. This paper proposes a BFSK-ZCZ-CD... 详细信息
