- 语音信号的频域处理,语音虽然是一个时变、非平稳的随机过程。但在短时间内可近似看作是平稳的。因此如果能从带噪语音的短时谱中估计出“纯净”语音的短时谱，即可达到语音增强的目的。由于噪声也是随机过程，因此这种估计只能建立在统计模型基础上。利用人耳感知对语音频谱分量的相位不敏感的特性，这类语音增强算法主要针对短时谱的幅度估计。 -voice signals in the frequency domain processing, voice

- 对于移动通信系统主要有两类衰落：大规模衰落和小规模衰落。大规模衰落表示由于大范围内移动而引起的平均信号能量的减少或路径损耗。而小规模衰落则表现为两种机制：信号的时延扩展和信道的时变特性。对于无线应用，信道的时变特性是由于发射机和接收机相对移动而造成传输路径的变化。这些传播条件的变化速率影响衰落率。如果存在大量反射路径而不存在视行信号分量，此时的小规模衰落称为瑞利衰落(Rayleigh fading)，接收信号的包络由瑞利概率分布函数统计
GPSInSAR
- InSAR是一种极具潜力的新型空间大地测量方法，但它也有其固有的限制，特别是受到大气层延迟（对流层延迟、电离层延迟等）、卫星轨道误差、地表状况和时变去相关性等影响，很容易导致InSAR图像解释错误，而InSAR数据本身无法解决所存在的上述问题。而GPS可以精密定位，可以较为精确地确定电离层、对流层参数，是当前应用最广泛的一种空间大地测量手段。-InSAR is a potential new space geodetic methods
