求解线性规划逆问题的光滑牛顿法的程序，时间很快，精确度也很高(Solving the inverse problem of linear programming procedure smooth Newton method, the time soon, is also very high accuracy)

多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流，从而使子数据流具有低得多的传输比特速率，利用这些数据分别去调制若干个载波。所以，在多载波调制信道中，数据传输速率相对较低，码元周期加长，只要时延扩展与码元周期相比小于一定的比值，就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现，如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中，OFDM可以抵抗多径干扰，是当前研究的一个热点。(Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data. )
