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 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )

好用地 matlab 区域增长算法，先输入比较范围，再输入种子点数目，然后就是手动选取种子点了 ，好运哦！(good land Matlab regional growth algorithm, importing more scope to import seed spots, Then, they manually select seed, good luck!)

全相位陷波器是全相位数字信号处理体系中一个很有特色的技术，在通信、军事等抗强干扰场合中应用及其广泛，因而研究全相位陷波器并仿真建模实现其滤波功能，具有很高的意义。(All-phase notch filter is a very distinctive technique in the all-phase of digital signal processing system. In communications，military and such resistance interference are widely used. Therefore, it is of high significance to the study of All-phase notch filter and simulate the modeling to realize the filter function)
