说明：  Matlab_FFT方法检测正弦波相位 (Matlab_FFT phase sine wave was detected)

支持向量机用于回归，在MATLAB里实现的。方便好用(Support vector machines for regression, implemented in MATLAB in. Is easy to use)

三角波及其频谱三角波及其频谱三角波及其频谱(The triangle spread the spectrum)

本源代码给出了伽利略卫星导航系统的码跟踪算法(source code is the Galileo satellite navigation system code tracking algorithm)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)
