电视视频噪声功率与加权压缩分析
This paper gives the ASE noise of fiber Raman amplifier with forward coupled equation,getting the losing of noise power brought by ASE noise,analyzing the relation between ASE noise power and attenuation of signal,as well as the length of fiber transmission.
通过此简化模型 ,得出了由ASE噪声引起的噪声功率损失 ,进而分析了ASE噪声功率与信号的衰减及传输距离的关
In light of the fact that the noise power is affected by the change of the channel order,a novel algorithm is proposed.
根据噪声功率随信道阶数的变化特点,提出一种新的阶数估计算法。
The concept of" equivalent noisy power spectral density" is introduced in this paper.
