中文说明:
为均衡带限信号所引起失真的横向或格型自适应均衡器(其中横向FIR系统长M=11), 系统输入是取值为±1的随机序列 ,其均值为零;参考信号 ;信道具有脉冲响应:
式中w用来控制信道的幅度失真(w = 2~4,例如,取w = 2.9,3.1,3.3,3.5等),而且信道受到均值为零、方差为 (例如,取 ,相当于信噪比为30dB)的高斯白噪声 的干扰。试比较基于下列五种算法自适应均衡器在不同信道失真、不同噪声干扰下的收敛情况(对应于每一种情况,在同一坐标下画出其学习曲线):
横向/格-梯型结构LMS算法[1-4]
横向/格-梯型结构RLS算法[1-4]
English Description:
In order to equalize the distortion caused by band limited signal, the transverse or lattice adaptive equalizer (where the length of transverse FIR system is m = 11) is designed. The system input is a random sequence with a value of ± 1 and its mean value is zero
