任意条件下数字光接收机灵敏度的计算
摘要
本文在考虑了码间干扰及量子噪声等实际因素影响的情况下
以Personick的高斯近似法为分析基础
得到了数字光脉冲电平数为任意整数
且这些光脉冲电平所出现的概率为任意分布时的数字光接收机灵敏度计算公式。
Abstract
Giving considerations to the actual influence caused by factors such as inter-symbol interference and quantum noise
this psper takes the Personick′s Gaussian approximation method as the analysing basis and gives out the sensitivity calculating formula for digital optical receiver when the number of digital optical pulse level is an arbitrary integer and the probability of the pulse level is distributed arbitrarily.
