Abstract
Space system noises are serious problems in spaceflight system, which appear in signal modulation, transmission, receiving and demodulation and greatly influence data precision. In order to solve problems of spaceflight system noises, this paper presents noise reduction processing method based on wavelet analysis combined with wavelet denoising theory. Wavelet noise reduction program is developed by using Matlab software and the noise reduction process is simulated. The results show that noise reduction processing method based on wavelet analysis can effectively reduce the spaceflight system noise.关键词
