使用下面的参数设计信道均衡器，其中使用两个独立的随机数发生器，一个用x(n)来表示，用来测试信道；另一个用v(n)来表示，用来模拟接收器中的加性白噪声的影响。序列x(n)是x(n)=±1的伯努利序列，随机变量x(n)具有零均值和单位方差。第二个序列v(n)具有零均值，其方差由信噪比决定。均衡器有11个抽头。(Use the following parameter design of channel equalizer, which uses two separate random number generator, one with x (n) to indicate, to test the channel the other with v (n) to indicate to simulate the receiver in The additive white noise. Sequence x (n) is x (n) = ± 1 of the Bernoulli sequence of random variable x (n) with zero mean and unit variance. The second sequence v (n) has zero mean, its variance decision by the signal to noise ratio. There are 11-tap equalizer.)

说明： 在MATLAB中表示信号的常规格式是向量或者矩阵。本示例中利用randint 函数来产生一个表示二进制数据序列连续值的列向量。其中二进制数据序列的长度（即为列向量中的行数）设置为30,000。
下面的代码同时还绘制了数据序列的杆图（stem plot），用来显示数据的0、1值。你所产生的图可能与次示例中的图有一点不一样，这是因为本示例中应用了随机数。
(Said signal in MATLAB conventional format is a vector or matrix. In this example use randint function to generate a column vector of a sequence of binary data, said successive values. Wherein the length of the binary data sequence (i.e., the number of rows in the column vector) is set to 30,000. The following code sequence of data is also plotted in Fig rod (stem plot), the value 0 is used to display the data. You may have generated the second example of FIG FIG little different, this is because the present example, the application of the random number.)
