信源为数字信号信道信噪比为10dB的直扩通信系统仿真实验-LDPC译码仿真源代码(Source to a digital signal channel 10dB SNR DSSS communication system simulation simulation-LDPC code decoding)

将实信号变换为复信号，提取信号幅值、相位角，计算相位同步指数，分析各组信号数据之间的同步稳定性。(The signal is converted into a complex signal, extraction of signal amplitude, phase angle, calculation of phase synchronization index, analysis of stability of synchronization between each signal data.)

使用Dijkstra进行初步路径规划，然后使用蚁群算法实现路径规划问题(Ant colony algorithm path planning problem)

说明：  灰度门限化许多情况，图象是由具有不同灰度级的两类区域组成。如文字与纸张、地物与云层（航空照片）。其特点:直方图具有两个峰，分别与两个灰度级范围相对应 。故可选择一个门限，将两个峰分开。(Gray threshold of many cases, the image is gray level of two different regional groupings. If words and paper, surface features and cloud cover (aerial photograph). Its features: histogram has two peak, respectively, with the two gray-scale range corresponding to. So choose a threshold, separating the two peaks.)

归一化算法，很好的源代码，好不容易找到的，分享一下。(Normalization algorithm, a good source code, hard to find, and share.)
