一种基于码谱数值算法的改进算法
An improved algorithm based on code spectrum numerical algorithm
摘要
Abstract
Code spectrum is a tool of analyzing the encoding performance and decoding complexity of distributed arithmetic coding,which can effectively improve the encoding performance. The numerical algorithm is usually used in code spectrum cal⁃culation,but it is an iterative calculation process,in which the time complexity is very high. To solve this problem,an im⁃proved algorithm based on code spectrum numerical algorithm is proposed,which simplifies the numerical algorithm by remov⁃ing the unnecessary functions. The correctness of the improved numerical algorithm is verified theoretically in the paper. The ex⁃perimental results show that the improved numerical algorithm can effectively improve the computational efficiency of code spec⁃trum,and broaden the practical application range of code spectrum.关键词
