We develop a distributed framework for realizing optimized quantizer that enables encoding CS measurements of correlated sparse sources followed by joint decoding at a fusion center. The optimality of VQ encoder-decoder pairs is addressed by minimizing the sum of mean-square errors between the sparse sources and their reconstruction vectors at the fusion center. We derive a lower-bound on the end-to-end performance of the studied distributed system, and propose a practical encoder-decoder design through an iterative algorithm.", "revisions": [ { "version": "v1", "updated": "2014-04-30T10:16:23.000Z" } ], "analyses": { "keywords": [ "compressed sensing", "distributed quantization", "fusion center", "enables encoding cs measurements", "vq encoder-decoder pairs" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1404.7666S" } } }
