速率自适应分布式信源编码的扩展子空间误差定位

Extended Subspace Error Localization for Rate-Adaptive Distributed Source Coding

Mojtaba Vaezi, Fabrice Labeau

摘要:

提出了一种基于离散傅立叶变换(DFT)码的速率自适应分布式信源编码(DSC)方法。删余DFT码可用于实现码率自适应信源编码,但由于子空间误差定位性能严重下降,即使在适度删余后,其性能也很差。所提出的基于子空间的错误定位扩展和改进了现有的一个,基于额外的伴随式,自然是适合于速率自适应分布式信源编码架构。

英文摘要:

A subspace-based approach for rate-adaptive distributed source coding (DSC) based on discrete Fourier transform (DFT) codes is developed. Punctured DFT codes can be used to implement rate-adaptive source coding, however they perform poorly after even moderate puncturing since the performance of the subspace error localization degrades severely. The proposed subspace-based error localization extends and improves the existing one, based on additional syndrome, and is naturally suitable for rate-adaptive distributed source coding architecture.
