Coding for the Slepian-Wolf problem with turbo codes
This paper proposes a practical coding scheme for the Slepian-Wolf problem of separate encoding of correlated sources. Finite-state machine (FSM) encoders, concatenated in parallel, are used at the transmit side and an iterative turbo decoder is applied at the receiver. Simulation results of system performance are presented for binary sources with different amounts of correlation. Obtained resu...
متن کاملPolar Codes for Nonasymmetric Slepian-Wolf Coding
A method to construct nonasymmetric distributed source coding (DSC) scheme using polar codes which can achieve any point on the dominant face of the Slepian–Wolf (SW) rate region for sources with uniform marginals is considered. In addition to nonasymmetric case, we also discuss and show explicitly how asymmetric and single source compression is done using successive cancellation (SC) polar dec...
متن کامل"Real" Slepian-Wolf codes
We provide a novel achievability proof of the Slepian-Wolf theorem for i.i.d. sources over finite alphabets. We demonstrate that random codes that are linear over the real field achieve the classical Slepian-Wolf rate region. For finite alphabets we show that decoding is equivalent to solving an integer program. The techniques used may be of independent interest for code design for a wide class...
متن کاملOn the redundancy of Slepian--Wolf coding
In this paper, the redundancy of both variable and fixed rate Slepian–Wolf coding is considered. Given any jointly memoryless source-side information pair with finite alphabet, the redundancy of variable rate Slepian–Wolf coding of with decoder only side information depends on both the block length and the decoding block error probability , and is defined as the difference between the minimum...
متن کاملChannel Coding Techniques with Emphasis on Convolutional and Turbo Codes
In this thesis, a family of low complexity convolutional codes is constructed, by modifying appropriately the trellis diagram of punctured convolutional codes. The goal is to improve performance at the expense of a reasonable low increase of the trellis complexity. Many new convolutional codes of various code rates and values of complexity are provided. In many cases, a small increase in comple...
