Noise Improving Code Elements Transmission
摘要
Abstract
In this paper,stochastic resonance is applied to improve code elements transmission. A series of code elements are generated by encoding characters in a text,and they act as the input signals of system. And then,get the translated text by decoding these received code words. The system is subject to additive and multiplicative noises which are both Gaussian. Increasing noise intensity gradually,the ratio of error characters in the translated text will decrease first,and increase later. There exists an optimal noise intensity,which reduces the ra-tio of error to the least level,and the performance of the system is at the best. In addition,in the process of improving signals transmis-sion,multiplicative noise shows its robustness. At last,discuss the influence on varying of threshold units number and system threshold for the system performance.关键词
