[其它] pNEUMA_mastersproject：编写的python文件可与pNEUMA数据集一起使用-源码

说明：概述 ：图片:: ：目标： ：ALT：文档状态..最终证章 ＃从大规模轨迹数据集中估算交通特征。此存储库中的代码是硕士论文的一部分。 无人机从pNEUMA实验获得的轨迹数据被链接到基础网络，以通过放置虚拟回路来获得网络中任何位置的宏观流量特性。 使用代码非常简单，首先将数据集转换为正确的格式，然后提取研究区域的网络，并将所有轨迹映射到该网络。 将虚拟环路放置在网络中的任何位置都可以获取宏观的流量特征。 有关更多信息，请参阅此存储库中的论文文本。 在不久的将来，将进行一些更新，编辑和错误修

[其它] Passive phase noise compensation for fiber-optic radio frequency transfer with a nonsynchronized source

说明：We propose a passive compensation fiber-optic radio frequency (RF) transfer scheme with a nonsynchronized RF stable source during a round-trip time, which can avoid high-precision phase-locking and efficiently suppress the effect of backscattering on

[其它] 基于状态空间模型的子频带语音转换算法

说明：语音转换是一项改变说话人声音特征的技术,该领域主流方法——基于高斯混合模型的全频带参数映射,会导致转换后的语音频谱产生帧间不连续性.本文针对以上问题提出了改进方案:首先引入状态空间模型来模拟语音动态变化特性,其次利用离散小波变换对语音低频和高频部分的参数分为子频带处理.文章最后用主观和客观实验对提出的算法进行的实验仿真和验证.
