Design and Analysis of Multi-Level Physical-Layer Network coding for Gaussian Two-Way Relay Channels
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2014年 第6期62卷 1803-1817页
作者: Chen, Zhiyong Xia, Bin Hu, Zixia Liu, Hui Shanghai Jiao Tong Univ Dept Elect Engn IWCT Shanghai 200240 Peoples R China Qualcomm San Jose CA 95110 USA
In this paper, we propose a multi-level physical-layer network coding (MPLNC) scheme that optimizes the relay performance for both symmetric and asymmetric traffic in a Gaussian two-way relay channel. The proposed MPL... 详细信息

作者: Hern, Brett Michael Texas A&M University
学位级别:Ph.D.
We consider a two-way relay channel in which two transmitters want to exchange information through a central relay. The relay observes a superposition of the transmitted signals from which a function of the transmitte... 详细信息

Signalling enhancement on multilevel turbo codes
收藏 引用
INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS 2008年 第7期21卷 791-798页
作者: Bayat, Oguz Shafai, Bahram Salehi, Masoud Ucan, Osman N. Osman, Onur Beykent Univ Elect & Commun Engn Dept TR-34500 Istanbul Turkey Northeastern Univ Dept Elect & Comp Engn Boston MA 02115 USA Istanbul Univ Elect & Elect Dept TR-34850 Istanbul Turkey Istanbul Commerce Univ TR-34378 Istanbul Turkey
The design of multilevel turbo codes using M-PSK is optimized to achieve a low bit error rate (BER). Unequal error protection is employed via group set partitioning in multi-stage decoding to minimize the error propag... 详细信息

Nulling and cancellation detector for MIMO channels and its application to multistage receiver for coded signals: Performance and optimization
收藏 引用
IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS 2006年 第5期5卷 1207-1216页
作者: Choi, Jinho Univ New S Wales Sch Elect Engn & Telecomm Sydney NSW 2052 Australia
In this paper, we address some performance issues of multiple input multiple output (MIMO) channels with a nulling and cancellation (N/C) detector, which is based on the QR factorization. We find a theoretical bit err... 详细信息

Noncoherent Block-Coded TAPSK and 16QAM Using Linear Component Codes
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2010年 第9期58卷 2493-2498页
作者: Wei, Ruey-Yi Lin, Tzu-Shiang Gu, Shi-Shan Natl Cent Univ Dept Commun Engn Jhongli Taiwan
In this paper, we derive minimum noncoherent distances of block-coded TAPSK (twisted amplitude and phase shift keying) and 16QAM (quadrature-amplitude modulation), both using linear component codes. According to the d... 详细信息
