| 摘 要： | 针对分数间隔盲均衡算法(T/4-FSE-CMA)收敛速度慢、稳态误差大的缺点,提出了一种基于正交小波变换分数间隔的神经网络盲均衡算法(T/4-FSE-WT-FNN).该算法采用四路子信道模型,以神经网络作为均衡器,同时,对均衡器的输入信号做正交小波变换并进行归一化,与基于正交小波变换的前馈神经网络盲均衡算法(WT-FN...

| Abstract: | A new blind equalization algorithm of neural network based on orthognal wavelet transform fractionally spaced equalizer(T/4-FSE-WT-FNN) is proposed to reduce the steady-state error and improve the convergence rate.Four sub-channels are used in the algorithm and neural network is adopted as the equalizer in each channel.Simultaneously,the equalizer input signal is carried out by the orthogonal wavelet transform and normalized.Compared with WT-FNN,T/4-FSE-CMA and T/4-FSE-WT-CMA algorithms,the proposed algorit... |
