Because the probability density function of MQAM signal obeys L-S distribution, so it may construct the algorithm of discerning with L-S distribution.

由于MQAM信号的概率密度函数服从莱斯分布，从而用莱斯分布来构造识别算法。

And when we take the wave function and square it, that's going to be equal to the probability density of finding an electron at some point in your atom.

当我们把波函数平方时，就等于在某处,找到一个电子的概率密度。

So, that's probability density, but in terms of thinking about it in terms of actual solutions to the wave function, let's take a little bit of a step back here.

这就是概率密度，但作为,把它当成是，波函数的解，让我们先倒回来一点。

So if we're talking about probability density that's the wave function squared.

如果我们要讨论概率密度,这是波函数的平方。
