IEEE 1st AESS European Conference on Satellite Telecommunications (ESTEL)
作者: Serrano-Velarde, Dimitri Lance, Emmanuel Fenech, Hector R-Guisantes, Georges Eutelsat SA Paris Ile De France France
This work describes a novel methodology for the dimensioning of a Ka-Band high throughput satellite (HTS) for broadband communications. The method is based on the optimization of performance for a forward link, as a f... 详细信息

20th European Signal Processing Conference (EUSIPCO)
作者: Wang, Z. Klaiber, M. Gera, Y. Simon, S. Richter, Th. Univ Stuttgart Dept Parallel Syst D-70569 Stuttgart Germany Univ Stuttgart RUS Comp Ctr D-70550 Stuttgart Germany
A Fast and Lossless Image Compression (FLIC) algorithm based on the median edge predictor and Golomb coder of JPEG-LS is presented. FLIC eliminates the gradient-based context model from the JPEG-LS standard, the most ... 详细信息

Data Compression Conference (DCC)
作者: Gera, Yurij Wang, Zhe Simon, Sven Richter, Thomas Univ Stuttgart Dept Parallel Syst D-70550 Stuttgart Germany Univ Stuttgart RUS Comp Ctr D-70550 Stuttgart Germany
While the context-based entropy coding and bias cancellation steps in the JPEG-LS standard are key features to its compression performance, these steps also enlarge the memory footprint, create dependencies in the dat... 详细信息

Workshop on Network coding, Theory and Applications (NetCod)
作者: Jay Kumar Sundararajan Parastoo Sadeghi Muriel Medard Massachusetts Institute of Technology Cambridge MA USA Australian National University Canberra ACT Australia
We propose a new feedback-based adaptive coding scheme for a packet erasure broadcast channel. The main performance metric of interest is the delay. We consider two types of delay - decoding delay and delivery delay. ... 详细信息

IEEE 74th Vehicular Technology Conference (VTC)
作者: Banani, S. Alireza Vaughan, Rodney G. Simon Fraser Univ Sch Engn Sci Burnaby BC V5A 1S6 Canada
An adaptive coding scheme for spectral efficiency improvement in eigen-MIMO is presented. It uses Reed-Solomon (RS) codes with non-adaptive QAM. Non-adaptive modulation is of interest since it reduces the high complex... 详细信息
