说明：  基于互质采样-分段相参积累多项式相位变换的微弱线性调频信号检测算法。该代码的相关论文以oral presentation的形式发表于2018年10月在南京举行的IET国际雷达会议。(Multi-component LFM parameter estimation via order-2 DPT (overlapping and coprime) Author: Dr. Shengheng LIU)

说明：  对序列进行重构后，计算对应的矩阵，针对不同的嵌入参数，得到不同的图形(Reconstruction of the sequence, the calculation of the corresponding matrix, for different embedding parameters, get a different graphics)

基于Matlab的 GUI的集成软件，功能包括： 1、海杂波模型仿真和统计分析（瑞利、韦伯、对数和K分布SIRP和ZMNL法）； 2、海杂波/波导参数估计（海杂波、多径和波导参数和雷达探测性能估计）； 3、实测海杂波数据统计分析。(Matlab' s GUI-based integrated software, features include: 1, sea clutter model simulation and statistical analysis (Rayleigh, Weber and K on the number and distribution of SIRP and ZMNL Act) 2, Sea Clutter/waveguide parameter estimation ( sea clutter, multipath and the waveguide parameters and the radar detection performance is estimated) 3, measured sea clutter data statistical analysis.)

LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 (LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
