Center node: "analysis by synthesis based quantization of compressed sensing measurements"
  Abstract: We consider a resource-constrained scenario where a compressed sensing- (CS) based sensor has a low number of measurements which are quantized at a low rate followed by transmission or storage. Applying this scenario, we develop a new quantizer design which aims to attain a high-quality reconstruction performance of a sparse source signal based on analysis-by-synthesis framework. Through simulations, we compare the performance of the proposed quantization algorithm vis-a-vis existing quantization methods.

Connected through hyperedge HE-1 (induced by source paper "channel optimized vector quantizer design for compressed sensing measurements"):
  with members:
    - "performance bounds for vector quantized compressive sensing"
    - "projection based and look ahead strategies for atom selection"
    - "regime change bit depth versus measurement rate in compressive sensing"
    - "optimal quantization for compressive sensing under message passing reconstruction"
    - "universal rate efficient scalar quantization"
    - "subspace pursuit for compressive sensing signal reconstruction"
