信号经过两个独立的信道传输,两个信道的信道复增益分别为 和 。 是独立同分布的复高斯随机变量,实部虚部独立、均值为0,实部虚部的方差都是1。采用某分集技术后输出的信噪比为 ,其中 是常数, 是在 之间均匀分布的随机变量。请就不同的 、 ,用仿真的方法画出 的累积分布函数。(signal after two independent Channel Tunnel, Channel 2 Channel Minute respectively, and gain. Independence is the same complex Gaussian distribution of random variables, is the imaginary part of the Department of independence, mean 0 and the real part of the imaginary part is a variance. Using a diversity of the output signal-to-noise, which is constant, is the uniform distribution between random variables. Please different, and simulation methods paint the cumulative distribution function.)

sample
A motion picture presents a continues phenomena as a sequence of frames. We perceive continuity by "filling in the gaps"
and "smoothing out " the missing information. While faster motion requires more frames during a given time period, there is
a point where more frames per second yield no further improvement. The "sampling speed" must be fast enough to allow
"appropriate averaging of dead times between frames", but need not accommodate motion too fast to be seen by a human.
The above description is somewhat analogous to sampling of audio signals. The sampling rate depends on how fast the
signals vary (the highest frequency we hear). Nyquist showed that sampling frequency exceeding twice the audio
bandwidth is sufficient to include all the signal information, preserving the finest details up to half the sampling rate
