The source codes for the quantization scheme based on polar lattices
Dear Editor and Reviewers: Please follow the below introduction to use this package. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ PolarQZ.m : This is the main file to show the lossy compression performance of polar lattices. You can check the realized distortion and the compression speed there. We gave three target distortions 0.10 0,14 and 0.20 for exmaples. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ LatticeQZ_Para_settings_FixSigma_s.m: The m file is to set the parameter of the polar lattices for fixed sigma_s and given target distortion we check the distance between Y and Y' in our paper. we calculate the flatness factor associated with the partition chain and obtain the proportions of the set F I and S for each level ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CalculateZn.m: This m file is used to prepare the Bhattacharyya parameters for the polar codes at each level. As we mentioned in our paper, the method is based on Tal and Vardy's method in "How to construct polar codes" ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ MultilevelYXXDensityFunc.m MultilevelYXOXDensityFunc.m MultilevelYPrimeDensityFunc.m MultilevelYXDensityFunc.m MultilevelYDensityFunc.m MutualInfoYXAll.m These are supporting files to evaluate the P(Y, X_{1:\ell-1}|X_{\ell}) P(Y, X_{1:\ell-1}|X_{\ell}) for each level. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
