Joint Source/channel Coding for Multiple Sources Transmission
نویسندگان
چکیده
In [1], a practical joint source/channel coding algorithm was proposed for the transmission of multiple images to reduce the overall reconstructed source distortion at the receiver end within a given total bit rate. In this paper, it is demonstrated that by joint coding multiple sources with such an objective, both improved distortion performance as well as reduced quality variation can be achieved at the same time. Experimental results based on multiple images and video sequences justify our conclusion.

Joint Source/channel Coding for Transmission of Multiple Sources
A practical joint source/channel coding algorithm is proposed for the transmission of multiple images and videos to reduce the overall reconstructed source distortion at the receiver within a given total bit rate. It is demonstrated that by joint coding of multiple sources with such an objective, both improved distortion performance as well as reduced quality variation can be achieved at the sa...
متن کاملSource-channel Coding for Gaussian Sources Over a Gaussian Multiple Access Channel
We consider the problem of distributed joint source-channel coding of correlated Gaussian sources over a Gaussian Multiple Access Channel (MAC). There may be side information at the encoders and/or at the decoder. First we specialize a general result in [16] to obtain sufficient conditions for reliable transmission over a Gaussian MAC. This system does not satisfy the source channel separation....
متن کاملJoint Source-Channel Coding on a Multiple Access Channel with Side Information
We consider the problem of transmission of several distributed correlated sources over a multiple access channel (MAC) with side information at the sources and the decoder. Source-channel separation does not hold for this channel. Sufficient conditions are provided for transmission of sources with a given distortion. The source and/or the channel could have continuous alphabets (thus Gaussian s...

متن کاملJoint Source-Channel Coding for Progressive Transmission of Embedded Source Coders
We present a scheme for joint source-channel coding for transmission of sources compressed by embedded source coders over a memoryless noisy channel. We nd an exact solution to the problem of optimal channel code allocation. Then we investigate the properties of the solution which allow us to transmit the source progressively while retaining the optimality at intermediate and nal transmission r...
