An Efficient Joint Source-Channel Decoder with Dynamical Block Priors
An efficient joint source-channel (s/c) decoder based on the side information of the source and on the MN-Gallager algorithm over Galois fields is presented. The dynamical block priors (DBP) are derived either from a statistical mechanical approach via calculation of the entropy for the correlated sequences, or from the Markovian transition matrix. The Markovian joint s/c decoder has many advan...
متن کاملAn Iterative Joint Source-Channel Decoder
We present a simple, effective iterative structure for joint source-channel decoding using global iterations between a source and channel decoder. The source decoder uses the Sequence Based Approximate Minimum Mean Square Error (SAMMSE) algorithm. The iterative structure is tested using both LDPC and turbo channel codes and simulations show significant performance gains over non-iterative syste...
متن کاملAn Enhanced Joint Source-Channel Decoder
Tandem coding and decoding has been demonstrated to yield arbitrarily low error rates provided a sufficiently large block length is used. When applied to practical systems that are inherently limited to a finite complexity and therefore to finite block lengths, such a strategy may be largely suboptimal. Indeed, a tandem decoding strategy ignores two types of information: the source memory and t...
متن کاملAn Integrated Joint Source-Channel Decoder for MPEG-4 Coded Video
The MPEG-4 video coding standard uses variable length codes (VLCs) to encode the indices of intra and inter macroblocks after discrete cosine transform and quantization. Although VLCs can achieve good compression, they are very sensitive to channel errors. Joint source-channel decoding (JSCD) is emerging as an efficient method for dealing with this sensitivity to channel errors. This paper prop...
متن کاملJoint Source-Channel Codes for MIMO Block Fading Channels
We consider transmission of a continuous amplitude i.i.d source over an L-block Rayleigh fading Mt × Mr MIMO channel when the transmitter has no channel state information. Due to strict delay requirements Shannon’s source-channel separation theorem becomes obsolete and the optimal performance requires a joint optimization of the source and channel variables. Our goal is to minimize the expected...
