载噪比核算与基础噪声相关,基础噪声是频率的函数,在10G内,每赫兹的噪声功率几近相同,所以热噪波的功率谱函数可以近似的表达为:覣(f)≈KT噪声功率PN的表达式如下:
The carrier-to-noise ratio is related to the fundamental noise. The fundamental noise is a function of frequency. In 10G, the noise power per hertz is almost the same, so the power spectrum function of the thermal noise can be approximated as: 覣 (f) ≈KT noise The expression of power PN is as follows:
