Description: 1.程序的设计思路
该程序用于对一个文件夹下的所有文件进行扰乱，使程序打不开（文本文件除外）。
扰乱算法，是把每个源文件的头部500字节保存到一个目的文件中，并记录该源文件文件名于目的文件中，源文件中的头部500字节用0代替。而目的文件为每个源文件提供的1k的固定长度存放头部500字节和源文件的文件名，源文件的修改后文件名为其信息在目的文件中的偏移序号，并且以.trick为后缀。
复原算法，就是以上过程的逆过程。
另外，考虑到文件扰乱的权限问题，本程序在执行扰乱时需要设置口令，执行复原时需要输入口令。-1. The design ideas for the program to a folder of all documents disruption, that process can not be opened (except for text files). Disrupt algorithm, is the source of each document in the head 500 bytes to preserve a purpose document, and the record of the source file name to its purpose document, the source of 500 bytes with the head instead of 0. The purpose document for each source document for the 1k fixed length of 500 bytes stored on his head and source files, and the source document after document, entitled amend its information in the document aims offset serial number, and to. trick for the suffix.

Description: In this paper, a novel demodulation structure in
high-frequency (HF) channel is introduced and studied.Frequency-offset estimation, ractionally spaced adaptive equalization and carrier recovery techniques are involved.Frequency-offset correction is carried out based on channel impulse response estimation. ractionally spaced adaptive equalization and carrier recovery are combined with nonlinear decision feedback loop structure and the initial value
of tap coefficients of equalization are obtained from the previous channel estimation. Simulation is conducted under channel parameters with respect to MIL-STD-188-110B using a Monte Carlo technique. The results show this novel demodulation structure is feasible and efficient in HF channel, the symbol error ratio can reach to 10− 3 in 12dB SNR.-In this paper, a novel demodulation structure in

Description: 文章介绍了平坦衰落下的频偏和同步联合恢复技术，能够有效应对时变的信道，并且不需要训练序列，给出了详细的仿真和分析，供大家学习-Two open-loop algorithms are developed for esti-
mating jointly frequency offset and symbol timing of a linearly
modulated waveform transmitted through a frequency-fl at fading
channel. The methods exploit the received signal’s second-order
cyclostationarity and, with respect to existing solutions: 1) they
take into account the presence of time-selective fading effects 2)
they do not need training data 3) they do not rely on the Gaussian
assumption of the complex equivalent low-pass channel process
and 4) they are tolerant to additive stationary noise of any color
or distribution.
