Distributed Source Coding for Satellite Communications
Inspired by mobile satellite communications systems, we consider a source coding system which consists of multiple sources, multiple encoders, and multiple decoders. Each encoder has access to a certain subset of the sources, each decoder has access to certain subset of the encoders, and each decoder reconstructs a certain subset of the sources almost perfectly. The connectivity between the sou...
متن کاملMIMO Channel Models for Satellite Communications
In recent years considerable attention has been drawn to the systems with multiple element transmitter and receiver arrays. It has been demonstrated both in theory and practice that multiple-input multiple-output (MIMO) systems offer the promise of increased capacity, high spectral efficiency and high gains by exploiting space-time processing techniques in particular space-time coding (STC) tec...
متن کاملJoint Source-Channel Coding for Video Communications
The compression or coding of a signal (e.g., speech, text, image, video) has been a topic of great interest for a number of years. Numerous results and successful compression standards exist. Source compression is the enabling technology behind the multimedia revolution we are experiencing. The two primary applications for data compressing are storage and transmission. Video transmission is the...
