针对目前流行的一种文件格式segy 处理的软件包，( Since the original SEG Y Data Exchange Format [revision 0, reference page 45] was published in 1975 it has achieved widespread usage within the geophysical industry. This widespread usage has brought about many proprietary variations. Since the publication of SEG Y rev 0, the nature of seismic data acquisition, processing and seismic hardware has changed significantly. The introduction of 3-D acquisition techniques and high speed, high capacity recording media dictate the need for revisions to the SEG Y rev 0 format. The major changes introduced by SEG Y rev 1 are: standardizing the location of header information needed for current processing practices and defining a SEG Y data set as a byte stream format. The SEG Technical Standards Committee strongly encourages producers and users of SEG Y data sets to move to the revised standard in an expeditious fashion. )

说明：  本文是关于小波分析的一段matlab编程代码，介绍了一些基本的方法(This article is a section on the wavelet analysis matlab programming code, and describes some of the basic methods)

Wireless sensor networks are new type of emerging networks with bunch of applications in all fields due to their low cost and low power scheme. As these networks follow open wireless communication, they undergo dynamic node problems and fault node detection due to malicious node activities.

语音增强系统，包括信噪比估计和传递函数，分段函数和重建函数(speech enhancement project, including Prior SNR estimate, noise PSD estimate, gain function, framing and over-lap add)

说明：  QAM信号，滚降系数分别为0.4，0.7，1.0，信噪比为20dB，信号有叫qpsk(QAM signal, roll-off coefficients were 0.4,0.7,1.0, SNR 20dB, QPSK signals are called)
