实验要求：在一张图上绘制三种二进制信号（即反极性信号、开关信号和正交信号）的误码率。这三种信号可以在几何上用“信号空间”中的点来表示。在反极性信号情况下，信号是±s(t)，每个都有能量E。开关信号也是一维信号，所以两个信号为0和s(t)，正交信号我们上课已讲过。要求信噪比为0：12dB。(Experimental requirements: to draw a diagram of three binary signals (i.e., reverse polarity signal, the switching signal and quadrature signal) BER. These three signals can be in the geometric point in the signal space. In the reverse polarity signal case, the signal is s (t), each have energy E. The switching signal is also a one-dimensional signal, so the two signals is 0 and s (t), the quadrature signals teach us have talked. Signal-to-noise ratio to 0:12 dB.)
