anfisedit-learing-method-
这是一个matlab中的一个非常实用的软件,值得一下·里面详细介绍了anfisedit 怎么操作,还有程序运行的结果,当然还有源代码,对于研究模糊推理的人员有帮助(This is a matlab in a very practical software, worth about which details how anfisedit operation, as well as the results of running, of course, the source code for research staff helpful fuzzy inference)

v06_03_dem_2up_arrange
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)
