认知中继网络包括一个主用户发射机和接收机，一个次用户发射机和接收机，以及一个放大转发中继。次用户发射机和中继从自然界获取能量。次用户共享主用户的频带进行数据传送，中继放大转发主用户发射机和次用户发射机的信号。次用户发射机和中继根据获取的能量和数据传送要求控制发射功率。功率控制建模为在能量因果约束、(Cognitive relay network includes a primary user transmitter and receiver, a secondary user transmitter and receiver, as well as an amplify and forward relay. Secondary user transmitter and relay obtain energy nature. Secondary users share a frequency band of the primary user data transmission, the relay amplification repeater primary user and a secondary user transmitter the transmitter signal. Secondary user transmitter and a relay and a data transfer request according to the energy obtained by controlling the transmission power. The power control is modeled as a causal constraints in energy,)

运用蚁群算法求函数最值，采取蚁群迭代。根据函数求出最大值(Ant colony algorithm is used to find the function minimum)

基于matlab采用匹配滤波器实现的PN码捕获与跟踪，对学习PN码捕获的朋友很有帮助(Matlab using matched filter based on the PN code acquisition and tracking, PN code acquisition in learning helpful friend)

计算余弦随机过程的相关函数和功率谱，并且做图示说明(Calculate the cosine correlation function of stochastic processes and power spectrum, and the icons do note)

定位曲线峰值大小及峰值点横坐标,并对结果进行图形化标示。(localization of the peak horizontal ordinate and amplitude for a curve)

根据输入值的大小和输出值得大小，绘制相应的曲线，功率谱图(The size of the input and output values ​ ​ worthy size, draw the curve of the power spectrum)

自己写的MATLAB程序，用于已知2个单位向量，求它们的旋转矩阵。非迭代法。 另有一个绝对定向程序。(Write their own MATLAB for 2 unit vector, known for their rotation matrix. The iterative method. There is another absolute orientation program.)

matlab迭代法代码，很不错，值得看看(iterative method matlab code, very good, worth a look)
