碩士 === 國立中正大學 === 電機工程所 === 96 === Because of the popularity of the Distributed Video Coding, the essay will transmitted a sequence of bit stream with the Laplacian noise through the Wyner-Ziv’s architecture. The difference of side information and the original image data will be assumed the Laplacian distribution. In implementation, it uses the effective way to store H matrix by recording the index of the position of 1’s. It saves a lot of memory space and the computations for LDPC code. By inputting the deviation, we can find out there is a determinative range of deviation that let the computation of LDPC converges to the original data.
