On the equivalence between the Godard and Shalvi-Weinstein schemes of blind equalization
收藏 引用
SIGNAL PROCESSING 1999年 第1-2期73卷 185-190页
作者: Regalia, PA Inst Natl Telecommun Dept Signal & Image F-91011 Evry France
Certain equivalences between the Godard and Shalvi-Weinstein schemes have been previously noted under special circumstances. We present here a simple proof for real signals that an equivalence can be established assum... 详细信息

Capacity Bounds Under Imperfect Polarization Tracking
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2022年 第11期70卷 7240-7249页
作者: Farsi, Mohammad Karlsson, Magnus Agrell, Erik Chalmers Univ Technol Dept Elect Engn S-41296 Gothenburg Sweden Chalmers Univ Technol Dept Microtechnol & Nanosci S-41296 Gothenburg Sweden
In optical fiber communication, due to the random variation of the environment, the state of polarization (SOP) fluctuates randomly with time leading to distortion and performance degradation. The memory-less SOP fluc... 详细信息

Concurrent Blind Channel Equalization in Impulsive Noise Environments
收藏 引用
CHINESE JOURNAL OF ELECTRONICS 2013年 第4期22卷 741-746页
作者: Li Sen Wang Yan Lin Bin Dalian Maritime Univ Coll Informat Sci & Technol Dalian 116026 Peoples R China
In some communication systems the transmitted signal is contaminated by impulsive noise with a non-Gaussian distribution. Non-Gaussian noise caused significant performance degradation to communication receivers. The n... 详细信息

Pilot decontamination for multi-cell massive MIMO systems using asynchronous pilot design and data-aided channel estimation
收藏 引用
PHYSICAL COMMUNICATION 2018年 30卷 76-85页
作者: Huy-Dung Han Dang-An Nguyen Van-Duc Nguyen Tien-Hoa Nguyen Zia, Muhammad Hanoi Univ Sci & Technol Sch Elect & Telecommun Hanoi Vietnam Quaid I Azam Univ Dept Elect Islamabad Pakistan
In this work, we investigate the pilot contamination problem in multi-cell massive multi-input multi-output (MIMO) systems. The conventional approaches to address pilot contamination for multi-cell MIMO systems impose... 详细信息

Blind Multiuser Detection in Frequency Domain for MC-CDMA Systems Using Particle Swarm Optimization
收藏 引用
WIRELESS PERSONAL COMMUNICATIONS 2010年 第3期54卷 447-466页
作者: Wen, Jyh-Hrong Chang, Chuan-Wang Hung, Ho-Lung Chien Kuo Technol Univ Dept Elect Engn Changhua Taiwan Natl Chung Cheng Univ Dept Elect Engn Chiayi Taiwan Tunghai Univ Dept Elect Engn Taichung 40704 Taiwan
In digital communication systems, the constant modulus algorithm (CMA) for blind multiuser detector has some disadvantage such as slow convergence speed and weight phase rotation. In this paper, we put forward a novel... 详细信息

PROCEEDINGS OF THE IEEE 1998年 第10期86卷 1987-2008页
作者: van der Veen, AJ Delft Univ Technol Dept Elect Engn DIMES NL-2628 CD Delft Netherlands
Deterministic blind beamforming algorithms try to separate superpositions of soul ce signals impinging on a phased antenna array by using deterministic properties of the signals or the channels such as their constant ... 详细信息

Ill convergence of minimum output energy infinite impulse response equalizer for digital vestigial sideband signals
收藏 引用
INTERNATIONAL JOURNAL OF ADAPTIVE CONTROL AND SIGNAL PROCESSING 2012年 第1期26卷 73-83页
作者: Chung, Wonzoo Korea Univ Sch Comp & Commun Engn Seoul South Korea
Minimum output energy (MOE) algorithm is a widely used adaptive algorithm for blind adaptation of infinite impulse response (IIR) filters. In this paper, we show that the MOE algorithm is not suitable for blind adapta... 详细信息

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 2000年 第6期E83A卷 1168-1174页
作者: Woo, DH Yoon, TS Byun, YS Univ Inchon Dept Elect Engn Inchon South Korea
The multiple access causes an interference problem in the direct-sequence code-division multiple process systems. An efficient adaptive algorithm should be used to suppress this interference for the improvement of sys... 详细信息
