标题: Ec/N0 还是Ec/No? [查看完整版帖子] [打印本页]

作者: duchoix 标题: Ec/N0 还是Ec/No?

最近做了很多关于测量报告的文档，其中有个说法让我很是纠结，就是不大清楚到底是Ec/N0还是Ec/No。我查了一些资料，虽然都说是noise，但是不知道为什么是数字0，而不是小写字母o。

为此，我去搜了下Ericsson,结果发现只有数字0的写法，而且可怜的是居然只有3个hits，去找了下Cisco,发现别个用的是EC/NO，去找3GPP,发现两个都有，hits也差不太多。

这下我可犯难了，如果是数字0的话，后面也没有1，2，3啥的，如果是o的话可以理解，是缩写，可是我去查了一个MR,发现脚本里却还真的是Ec/N0，这让我咋办？

大家看到的给个见解哈，谢咯～

会不会是格式的问题。因该是noise。

我是学通信的，我知道，这个叫Ec/Io，都是字母来的，我从没听过有I零的的说法

3GPP协议里边是两个都有，好不清楚啊！

下边取自协议里边，关于S准则的：
