| Abstract: | This article focused on the communication system may be introduced in the various noises, noise and the corresponding method of calculation. And it also introduced a useful signal to measure the noise impact of the parameters - the equivalent noise temperature and noise factor, the noise factor and the definition, calculation methods. Noise to understand the impact of the communications system, provides the reference to the reduced noise＇s influence. |
