相反数

我们可以先用一下，然后加个负号，但是我要说明，ndS正好是这个的相反数。

Well , we could use it and then subtract , but I was just going to say that ndS is actually the opposite of this .

Thus you do not get a finite number of stable configurations , but an infinite number .

调制阶数越低，频谱利用率就越低，但系统误码率较小；相反调制阶数越高，在提高了频谱利用率的同时，却增大了系统的误码率。

When modulation order is low , the spectrum utilization rate will be lower , but the system bit error rate will be smaller .
