Joint source-channel coding with allpass filtering source ...
In this paper, we proposed a fixed-length robust joint source- channel coding (JSCC) scheme for image transmission over noisy channels. Three channel models are studied: binary symmetric channels (BSC) and additive white Gaussian noise (AWGN) channels for memoryless channels, and Gilbert-Elliott channels (GEC) for bursty channels....

3. Joint source channel coding. The aim of joint source channel coding is to increase the robustness of the transmission chain by reducing the impact of errors on the quality of the reconstructed image while keeping the system as simple as possible....

power etc, there is always trade-off between source coding and channel coding. Shanon has given separate source channel coding transmission system [1]. Using Joint Source Channel Coding (JSCC) recent wireless communication technology lead to robust and reliable image transmission [ 2] [3].The basic block diagram consists of source...

The goal of JSCC is to minimize the overall distortion under a given resource (coding bits) constraint, by optimally allocating source coding and channel-coding bits. B. Hash ......

Joint Source-Channel Coding for Deep-Space Image Transmission using Rateless Codes O. Y. Bursalioglu, G. Caire, and D. Divsalar Abstract A new coding scheme for image transmission over noisy channel is proposed. Similar to standard image compression, the scheme includes a linear transform followed by successive refinement scalar quantization....
LDPC-based Joint Source Channel Coding and Decoding ...
We define the R s c = l n as the source coding rate, and R c c = l m as the channel coding rate. The overall rate of the system is R = n m. The LDPC-based JSC message-passing decoding is performed on a Tanner graph with the BP algorithm by exchanging extrinsic log-likelihood ratios (LLRs) between the source and the channel LDPC decoders....

source–channel coding for the transmission of still images. In [3], Farvardin and Vaishampayan provide an algorithm for minimizing total distortion caused by the quantization and channel noise. Later, the same researchers present a method for the joint source–channel coding of a scheme based on the two-dimensional block cosine transform for...
Joint Source-Channel Coding at the Application Layer for ...
The convex nature of the rate-distortion function, computed by means of reverse water-filling, allows us to solve relevant convex optimization problems corresponding to different performance criteria. Then, layered joint source-channel codes are constructed based on the concatenation of embedded scalar quantizers with binary rateless encoders. I....
