中文说明：
假设每个延时单元延时10ms。被传输的基带信号x(t)是一个0，1交替变换的矩形二进制脉冲序列，脉宽为10ms，并假设x(t)通过一个稳定的散射信道后才到达均衡器，成为2径信号，这两路信号幅度相等 ，相隔15ms。用MATLAB实现一个2级LMS均衡器。
English Description：
It is assumed that each delay unit delays for 10ms. The transmitted baseband signal x (T) is a 0,1 alternating rectangular binary pulse sequence with a pulse width of 10ms. It is assumed that x (T) reaches the equalizer after passing through a stable scattering channel and becomes a two-way signal. The amplitudes of the two signals are equal and separated by 15ms. A two-level LMS equalizer is realized with MATLAB
