Complex networks have some common basic model, such as random graph, WS small-world networks, NW small-world networks and scale-free BA network, the program generated from the mechanism of these networks to generate the complex network model and analysis its basic nature, such as the average path length.

OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)
