QAM，(正交振幅键控调制)，输出为QAM调制产生的复包络信号

聚类分析中的划分聚类算法的k-means算法（随机选取矩阵数据）(Partition clustering algorithm in clustering analysis of k- means algorithm (random matrix data))

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.)

用matlab 中的simulink模块编写的引擎 包含子系统等 运行无问题(Using matlab simulink module written in engine contains no problem running subsystems)

代码里有很完整的注释和解释，包含特征值与特征向量的提取、训练样本以及最后的识别，验证可用，预报误差法参数辨识-松弛的思想，直线阵采用切比学夫加权控制主旁瓣比，利用自然梯度算法。

Fitness function that help users to use that in ga applications.

RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。(RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。 RD algorithm is the most important processing algorithm in processing SAR, in the far field approximation, the two-dimensional separation into two one-dimensional processing, reduces the amount of computation, good imaging effect. )

it will help the beginners to understand digital image processing using matlab
