MATLAB-DUO-HUANG-FANGZ

this is a algorithm Fast PCA, it is very suitable for beginer who want to understand PCA, it is demo step by step

运用MATLAB仿真，实现机器人的避障。(Achieving obstacle avoidance for robots)

此代码是计算两个数据之间的相关性的，直接调用Matlab里的功能函数(This code is to calculate the correlation between the two data directly call Matlab functions)

说明：  用于速度控制的联合仿真可实现对四轮小车的不换控制。(The joint simulation for speed control can realize the non-replacement control of four-wheeled car.)

GUI for digital watermarking with four methods: LSb, LSB by concatenation, DCT , DWT in matlab

说明：  为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环 谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频 率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信 噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2 tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2 able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the decision threshold correspond to different false alarm probability , as a result , making the sensing users can detect licenced users signal under lower signal in noise ratio (SNR) .)
