m分别使用ESN网络,ESN+RBF神经网络以及ESN+Volterra网络进行数据预测对比仿真

1.算法描述 ESN是Jaeger于2001年提出一种新型递归神经网络，ESN一经提出便成为学术界的热点，并被大量地应用到各种不同的领域中，包括动态模式分类、机器人控制、对象跟踪核运动目标检测、事件监测等，尤其是在时间序列预测问题上，取得了较为突出的贡献。Jaeger本人在提出这种神经网络的第二年便在国际知名期刊上发表了关于将ESN网络用于时间序列预测的文章，为后来其发展做出了巨大的贡献。另...

m基于RBF神经网络和BP神经网络的信道估计误码率matlab仿真

1.算法描述在无线通信系统中，从发射端发射的信号，经过直射、反射、散射等路径到达接收端。在ofdm系统中，为了获取更好的性能，需要进行信道估计获取信道的状态信息。ofdm技术虽然可以通过添加循环前缀的方式抑制多径效应产生的符号间干扰，但是却对高速移动产生的多普勒效应极其敏感。典型的信道估计方法包括最小二乘法和最小均方误差法，然而在系统发射端和接收端的相对移动速度较快时，这两种方法性能受限...
