International Conference on Autonomic Computing (ICAC)
作者: S.M. Sadjadi P.K. McKinley R.E.K. Stirewalt B.H.C. Cheng Software Engineering and Network Systems Laboratory Department of Computer Science and Engineering Michigan State University East Lansing MI USA
Adaptable applications are difficult to develop and maintain especially if adaptive code, which implements the adaptive behavior, is tangled into functional code, which implements the imperative behavior. Our work inv... 详细信息

International Conference on Communication Systems
作者: Takki Yu Sangchul Han Daesik Hong Changeon Kang Information and Telecommunication Laboratory Department of Electrical and Electronic Engin. Yonsei University Seoul South Korea
A generalized adaptive code acquisition scheme is proposed by using a multi-layer structure. The backpropagation network (BPN) is used in modeling the multilayer system. The timing offset of the received code can be d... 详细信息

International Workshop on Antenna Technology: Small Antennas and Novel Metamaterials, iWAT
作者: Hua-Lung Yang Wen-Rong Wu Department of Communication Engineering National Chiao Tung University Hsinchu Taiwan
The paper proposes a novel code acquisition scheme employing an adaptive beamformer and an adaptive temporal filter. Conventional code acquisition with beamforming requires a code-phase testing procedure which can be ... 详细信息

International Conference on Telecommunications (ICT)
作者: I. Gutierrez F. Bader A. Mourad Advanced Technology Standards and Regulation (ATSR) Samsung Electronics Research Institute London UK Centre Tecnològic de Telecomunicacions de Catalunya Barcelona Spain
In this paper the spectral efficiency using combinations of Transmit Antenna Selection with Linear Dispersion Code Selection (TACS) is studied. The selection criterion is defined in order to maximize the spectral effi... 详细信息

IEEE International Conference on Multimedia and Expo (ICME)
作者: M. Sehlstedt J.P. LeBlanc Division of Signal Processing Luleå University of Technology Lulea Sweden
We investigate physical layer opportunities resulting from multimedia streams which use progressive coding. With such progressively encoded video frames the location of the first bit error is more important than the o... 详细信息

GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270)
作者: Takki Yu Jonghyung Kwun Hyounggoo Jeon Daesik Hong Changeon Kang Dept. of Electronics Yonsei Univ. Seodaemungu Seoul Korea Dept. of Information and Communications Engineering Dongeui Univ. Pusan Korea
In this paper, a noncoherent adaptive code acquisition scheme is proposed by combining an adaptive filter with a differential detector. The carrier phase offset in the PN signal component of the filter input is remove... 详细信息

IEEE Conference and Exhibition on Global Telecommunications (GLOBECOM)
作者: Jik Dong Kim Sang Wu Kim Department of Electrical Engineering Korea Advanced Institute of Science and Technology Daejeon South Korea
We consider a combined power/code rate adaptation in Reed-Solomon (RS) coded frequency-hopped spread-spectrum multiple access (FH/SSMA) communications, where the transmission power and code rate are adapted simultaneo... 详细信息

International Conference on Green Circuits and Systems (ICGCS)
作者: Minjie Chen Pasi Fränti Mantao Xu School of Computing University of Eastern Finland Joensuu Finland School of Electrical Engineering Shanghai Dianji University Shanghai China
Bit-plane coding has been widely used in lossless compression of gray-scale images or color palette images. In the context-based encoding procedure, the values of previous significant planes are also considered, which... 详细信息
