说明：  QPSK调制的ofdm仿真，采用matlab语言编写，忽略了信道估计等部分。(QPSK modulation ofdm simulation using matlab language, ignore the part of the channel estimation.)

uploaded the polar codes for cooperative relay networks and the same can be used for compression

要求：从x(t)=sin(2*pi*5*t)+sin(2*pi*200*t)+sin(2*pi*50*t)信号中滤出频率为5Hz的信号(Requirements: from x (t) = sin (2* pi* 5* t)+ sin (2* pi* 200* t)+ sin (2* pi* 50* t) signal to filter out the signal frequency of 5Hz)

窄带信号生成，生成窄带信号，可以自己调节信号的基础信息(Narrow-band signal generation)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元数为10，快拍数为200，信噪比为20dB，阵元间距分别为 tambada/6 tambada/2、tambada。(Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element number 10, the number of snapshots for 200, SNR is 20dB, respectively array element spacing  tambada/6 tambada/2, tambada.)

深度优先搜索算法Matlab源码 ％ 此程序从国外网站收集得到，是标准的深度优先搜索算法，可实现节点遍历和检测回路的功能，详细情况请看原英文注释 ％ 我在此程序中添加了随机性，即遇到分叉时，随机选下一个节点，成为随机深度优先搜索算法(Depth-first search algorithm Matlab source this procedure site collected from abroad, is the standard depth-first search algorithm, can be achieved and the detection circuit node traversal functions, details see the original English Notes I added this procedure randomness, that is, bifurcation encountered when a randomly selected node, become a random depth-first search algorithm)

本程序是用于信号相关分析的实验程序。 主要功能是计算和比较几种信号的相关函数。( This procedure is experimental procedure for signal correlation analysis. The main function of the correlation function is calculated and compared several signals.)
