Abstract
Wyner-Ziv coding is a lossy compression technique which uses the decoder side information to help reconstruction. We propose a practical code design methodology and a quantization algorithm inspired by successive quantization
to solve the Wyner-Ziv problem in quadratic Gaussian case. Our coding structure uses two independent component codes and this coding structure has been proven to achieve the Wyner-Ziv bound by the random coding analysis.
We also implement it with existing rate-distortion-bound-achieving quantizer and capacity-achieving channel code. Compared to the existing binningbased design approaches, our design methodology and quantization algorithm have reasonable complexity with good performance.
