此程序参照了IEEE 802.11a ，使用了52个子载波。理论期望papr为52.但是由加扰器的存在，所有子载波很难一直的调制(Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely. )

feature selection from iris data set it will use statistical methods and get the best set of features then use graphs to classify the data

运行结果良好的三个RLS算法，供大家参考使用(good operating results in three RLS algorithm, for reference use)

说明：  用精确线搜索的共轭梯度法，求问题的极小点(Using the conjugate gradient method of exact line search to find the minimum point of the problem)

this program is about the BER of ofdm_4QAM. I hope it will do a little help for somebody .
