摘要：

We consider the distributed compression of two (binary memoryless) correlated sources and propose a unique codec that can reach any point in the Slepian-Wolf region. In a previous method based on channel codes, the decoder multiply the compressed data by an inverse submatrix of the code. This multiplication presents two drawbacks. First, if turbo codes are used, the submatrix has no periodic structure SA. the whole inverse has to be stored and no fast implementation exists for the multiplication. Second, this multiplication may lead to error propagation. In this paper, we propose a method that is both robust and fast.
