IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Zhenga He Jihong Zhang Yiming Mao Radio Engineering Department South-East University Nanjing China
The authors developed a new adaptive image coding technique using interpolative mixed vector quantization (VQ) which mixes the 2D discrete cosine transform (DCT) with VQ. A median filter is first used to eliminate fin... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Y. Tanaka T. Taniguchi Fujitsu Laboratories Limited Kawasaki Japan
The authors propose an efficient vector quantization scheme and a novel linear predictive coding (LPC) analysis scheme, both of which exploit interframe correlation in the successive spectrum envelope of speech signal... 详细信息

AN APPLICATION OF THE HOPFIELD MODEL TO HUFFMAN CODES
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 1993年 第3期39卷 1071-1076页
作者: FABRIS, F DELLARICCIA, G Dipartimento di Matematica e Informatica Universita degli Studi di Udine Udine Italy
The discrete neural network model due to Hopfield (1982), and his following developments, allow to tie the dynamical evolution of a neural network to a quantity-the energy of the network-which is monotonically decreas... 详细信息

AN adaptive coding SCHEME FOR TIME-VARYING CHANNELS
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 1991年 第5期39卷 653-663页
作者: VUCETIC, B UNIV SYDNEY SCH ELECT ENGNSYDNEYNSW 2006AUSTRALIA
This paper presents an adaptive coding scheme for digital communication over time-varying channels. The scheme is based on a finite-state Markov channel model. Emphasis is on the adaptation of the error protection to ... 详细信息

IEEE Singapore International Conference on Networks
作者: M.L. Lin R.H. Deng Department of Electrical Engineering National University of Singapore Singapore
Type I hybrid ARQ systems use an error-control code of fixed rate for error-correction in each transmitted packet. In such systems, the code rate must be carefully chosen to match the channel bit error rate (BER) in o... 详细信息

IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS 1992年 第5期10卷 884-891页
作者: ERSOY, OK NOUIRA, A School of Electrical Engineering Purdue University West Lafayette IN USA
The discrete cosine-III transform (DC3T) is the same as the discrete symmetric cosine transform (DSCT) with a specific preprocessing of input data. It has less computational complexity than the discrete cosine transfo... 详细信息
