Okumura_Hata
说明： 日本科学家奥村通过对城市进行大量无线电波传播损耗的测量，得出了一系列经验曲线用于无线蜂窝网络的规划设计。在这些经验曲线的基础上，推出了简化的Hata模型。(Olympic Village by Japanese scientists a great deal of radio waves in urban propagation loss measurement, the experience curve obtained for a series of planning and design of wireless cellular networks. In the curves on the basis of these experiences, the introduction of a simplified Hata model.)

timedomaincharactersticsanalysis
设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。
对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。
(Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file.
The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)
