A COMPARISON OF SCALAR QUANTIZATION STRATEGIES FOR NOISY CHANNEL DATA-TRANSMISSION
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 1995年 第2-4期43卷 738-742页
作者: CHEUNG, MY VAISEY, J Simon Fraser University Burnaby BC CA School of Engineering Science Simon Fraser University Burnaby BC Canada
It is known that the combination of uniform quantization and entropy coding performs optimally at asymptotically high rates. However, due to synchronization problems resulting from the use of variable length codes, th... 详细信息

Lossy predictive coding of SAR raw data
收藏 引用
IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING 2003年 第5期41卷 977-987页
作者: Magli, E Olmo, G Politecn Torino Dipartimento Elettron I-10129 Turin Italy
In this paper, we propose to employ predictive coding for lossy compression of synthetic aperture radar (SAR) raw data. We exploit the known result that a blockwise normalized SAR raw signal is a Gaussian stationary p... 详细信息
