matlabtosolve
基于MATLAB实现的说话人识别程序,分别用bp、pnn、som、rbf、lvq等算法,对语音文件进行训练和测试,效果不错。~..~
下面说明一下bprengong程序:
数据分别用来训练和测试两部分。
具体程序分为两部分,第一部分为:计算识别模型 变量v是mfcc处理以后的矢量。因为数据可能长短不一,所以放在同一进行截取。p的每一行代表一个语音数据(共15个)。变量Pr为每一行的最大最小值。变量T为目标值。输出神经元个数为15。
在训练阶段,如果用于训练的输入训练样本的类别标号为i(即语音数据的标号),则训练时设第i个节点的期望输出设为1。其余节点期望输出均为0。
在识别时,当一个未知类别的样本作用到输入端时,考查各输出节点的输出,并将这个样本的类别判定为输出值最大的那个节点对应的类别。

Modeling-Rayleigh-fading-channel-based-on-modifie
This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model.
A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-correlation.
alpha_n = frac{pi(n-0.5)}{2M} and eta_n = frac{pi n}{M},
results in the following model, usually termed the Dent model or the modified Jakes model:
R(t,k) = sqrt{frac{2}{M}} sum_{n=1}^{M} A_k(n)left( cos{eta_n} + jsin{eta_n}
ight)cos{left(2pi f_d t cos{alpha_n} + heta_{n}
ight)}.
The weighting functions A_k(n) are the kth Walsh–Hadamard sequence in n. Since these have zero cross-correlation by design, this model results in uncorrelated waveforms. The phases ,! heta_{n} are initialized randomly and have no effect on the correlation properties. Matlab fast Walsh-Hadamard transform function is used to efficiently generate samples using this model.
