A variable step uniformquantization(VSUQ) sum-product algorithm(SPA) was developed to reduce the hardware complexity of low-density parity-check(LDPC) code decoding.
为降低低密度奇偶检验码译码的硬件实现复杂度,提出了一种可变步长均匀量化“和积”译码算法。

The distance of the uniform color space is used as the distortion measure, and the codebook of vector quantization is used to set the color table register, which shows good results.
