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.)
