Summary:
This paper considers Slepian-Wolf (SW) coding in which side-information (SI) has insertion and deletion errors, presuming that the SI is given as a binary vector generated by temporal and/or spatial interpolation or extrapolation of related binary vectors. The coding could be regarded as a simplified model of SW coding in distributed video coding. From the generation process of SI vector, we define a hypothetical error model in the SI vector as an insertion/deletion/substitution error channel, and then show a coding scheme using nonbinary LDPC code. Decoding is based on an iterative multi-path decoding of forward-backward algorithm and FFT sum-product algorithm. Simulation results show the relations between insertion/deletion probability and decoded bit error rates.
