International Conference on Communications and Information Technology
作者: Mohamad Sayed Hassan Ammar El Falou Charlotte Langlais Alten Sir Universite de Rennes 1 Institut Mines-Telecom
In this paper, we investigate two approaches which deal with the construction of space-time block (STB) codes for a system possessing a forward error correcting (FEC) code at the transmitter side. The first approach d... 详细信息

International Conference on Distributed Computing Systems
作者: S.M. Sadjadi P.K. McKinley Software Engineering and Network Systems Laboratory Michigan State University East Lansing MI USA
We propose an adaptive CORBA Template (ACT), which enables run-time improvements to CORBA applications in response to unanticipated changes in either their functional requirements or their execution environments. ACT ... 详细信息

Data Compression Conference (DCC)
作者: B. Ryabkot J. Astola Siberian State Univ. of Telecommun. & Comput. Sci. Tomsk Russia Technical University of Tampere Finland
For many adaptive codes the speed of coding depends substantially on the alphabet size. In this paper we suggest a method for speeding up codes based on the following main idea. Letters of the alphabet are put in orde... 详细信息

IEEE Aerospace Conference
作者: Sandeep Mukherjee Mauro De Sanctis Tommaso Rossi Ernestina Cianca Marina Ruggieri Ramjee Prasad University of Roma "Tor Vergata" Via del Politecnico Aalborg University Center for TelelnFrastruktur (CTIF)
In this paper an analysis on the use of adaptive coding and Modulation (ACM) techniques for EHF satellite communications is presented with reference to the DVB-S2 standard. The analysis is focused on W-band communicat... 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 Conference on Wireless Communications and Networking
作者: Stephen Taylor Parastoo Sadeghi Research School of Information Sciences and Engineering Australian National University Canberra ACT Australia
We consider the problem of modelling a randomly time-varying frequency-selective fading channel as a finite-state Markov channel (FSMC). For a fading channel with two correlated taps and given statistical parameters, ... 详细信息
