基于隐藏密钥可以，将秘密信息msg嵌入到二值载体图像cover，算法简单，主要适合于将密文隐藏在BMP格式的文档里。(Key can be based on hidden, secret information will be embedded into the binary vector msg image cover, simple algorithm, mainly for the cipher text hidden in the BMP format documentation.)

在matlab simulink中建立动态相量分析模块，并对信号进行动态相量分析，验证其有效性(the dynamic phasor analysis module is built at matlab simulink, a signal s dynamic phasor is analized to test this module)

LDPC编码研究与分析，包含基本原理与算法及程序(Low Density Parity Check codes)

基于多相结构的信道化发射机实信号输出matlab仿真程序:从仿真得到的图可以看到，输出8路实信号所需的带宽为输出8路复信号所需带宽的一半。另外，输出的复信号频谱结构不再像直接法实现时所得到的顺序对应结构，其原因还有待进一步研究。(Channel based on multi-phase structure of real signal of the transmitter output matlab simulation program: graph obtained from the simulation can be seen, the output 8-channel bandwidth needed for real signals, the output 8-channel half the bandwidth required for complex signals. In addition, the output structure of the complex signal spectrum is no longer realized as the direct method corresponds to the order obtained by the structure, the reason remains to be further studied.)
