帕金森患者音频数据库
PD数据库由训练和测试文件组成。培训数据属于20名PWP（6名女性，14名男性）和20名健康人（10名女性，10名男性），他们在伊斯坦布尔大学Cerrahpasa医学院神经系上诉。从所有主题，采取多种类型的录音（26个声音样本，包括持续元音，数字，单词和短句）。从每个语音样本中提取一组26个线性和时间 - 基于频率的特征。由该专家医师确定的每个患者的UPDRS（（统一帕金森氏病评分量表）分数也可用于该数据集）因此，该数据集也可用于回归。 在收集由多种类型的录音组成的训练数据集并进行实验后，根据所获得的结果，我们继续在相同条件下通过同一医生的检查过程收集来自PWP的独立测试集。在收集这个

基于训练序列的信道估计研究
道估计是指描述物理信道对输入信号影响而进行研究的过程，其目的在于识别每组发送天线与接收天线之间的信道冲激响应。本文主要研究了基于训练序列的信道估计, 首先阐述了无线信道中信号的传播方式、信号的损失以及衰落效应、多径效应、时变效应等特性。接着在介绍信道特性的基础上着重介绍了比较经典的时域和频域信道估计方法，并从时域的角度介绍了最小二乘算法。最后对基于训练序列的信道估计进行仿真实验，比较均方误差大小，给出仿真曲线和结果分析。
