最近在弄关于CDMA的东西，所以找了一些资料 ，也就把这个提供给大家共同分享(GOOD)

考虑了瑞利衰落信道下的情况,设置了5,10,20条多径,有完美的仿真结果(consideration of Rayleigh fading channels under the conditions, the number of trails 5, 10, 20, a perfect simulation results)

In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a U.S. Federal Information Processing Standard. SHA stands for "secure hash algorithm".

计算时间序列的排列熵，来度量序列的复杂性(Measure the complexity of a time series by computing the permutation entropy)

这是一个比较有用的小程序，能对被水印出理过的图象进行检测，效果很明显．(This is a relatively small program useful, can be a watermark image over the rationale for testing, the effect is obvious.)

BGA布线手册，很好，很强大！搞硬件的朋友可以看看！！！(BGA layout，very good ！)

说明：  计算光纤模式 Optical signal sources that are capable of generating wavelength tunable ultra-short pulse train with high quality and high repetition rates play an important role in the optical networks(fiber mode)

Advanced correlation filter synthesis algorithms to achieve rotation invariance are described. We use a specified form for the filter as the rotation invariance constraint and derive a general closed-form solution for a multiclass rotation-invariant filter that can recognize a number of different objects. By requiring the filter to minimize the average correlation plane energy, we produce a multiclass rotation invariant (RI) RI-MACE filter, which controls correlation plane sidelobes and improves discrimination against false targets. To improve noise performance, we require the filter to minimize a weighted sum of correlation plane signal and noise energy. Initial test results of all filters are provided
