一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 (128 of an OFDM symbol of a valid symbol 128 inserted virtual sub-carrier Symbol rate (the effective data rate) fsymbol sending rate (including virtual subcarriers) 2fsymbol Of the input data needs to be 2 times the transmission data rate, in order to carry out the interpolation, to achieve the bit timing tracking, i.e. four times the sampling rate modulation signal fsymbol OFDM symbol Nfft = 128 points One OFDM symbol data points nfft* 2 = 256, the Guard Interval dot = Ng* 2 = 64)

This is the second part of special handling, that makes PTRACE_LDT possible to implement.

计算Lyapunov指数的Wolf算法，本算法为Matlab(Calculation of Lyapunov index Wolf algorithm, the algorithm for Matlab)

用matlab编写的信号处理之QPSK调制与解调程序,均衡,OFDM仿真,小波变换,卡尔曼滤波等等14个程序源代码(Written by matlab signal processing of the QPSK modulation and demodulation process, a balanced, OFDM simulation, wavelet transform, Kalman filtering, etc. 14 source code)

对于初学matlab 的人来说 ，这些小程序很基础，但是很有用，对以后大的程序有很大的帮助。(For beginners matlab people, these small program is very basic, but useful for future large program of great help.)

说明：  以上是关于超连续谱的一些英文资料，这些资料很好的介绍的超连续谱的成因，以及通过分布傅里叶方法模拟超连续谱形成的过程(These are some on supercontinuum information in English, the information super good introduction to the causes of a continuous spectrum, and by Fourier method simulation of the formation process of supercontinuum)
