基于DCT的数字水印matlab编程实现源码(DCT-based digital watermarking matlab programming source code)

以新型混沌系统———Liu系统为例,运用Matlab对混沌系统进行建模和动态仿真,分析了其动态仿真在混沌控制与同步中的应用,并对仿真结果作了简要的说明和讨论. (--- Liu chaotic system with a new system, for example, use of Matlab to the chaotic system modeling and dynamic simulation analysis of its dynamic simulation in the chaos control and synchronization of applications, and simulation results gave a brief description and discussion.)

GMSK信号调制和解调的仿真代码，包含一比特差分、2比特差分、鉴频等常用GMSK解调方案.之前上传的GMSK Modem差分相干、2比特差分解调存在问题。(GMSK demodulation schemes including one bit differential decoding, two bit differential decoding, differential coherent and digital frequency discriminating methods.)

无线通信信道信息的最小均方误差估计的时域均衡函数(The wireless communication time-domain MMSE channel equalization information)

The current MATLAB program of HHT includes the following modules: 1) eemd.m. The module that performs EMD/EEMD 2) ifndq.m. The module that calculates an instantaneous frequency for a given IMF and 3) extrema.m. A supporting module that is used by the previous two modules. 　 4) significance.m This is used to obtain the percenta line based on Wu and Huang (2004). 　 5) dist_value.m This is a utility program being called by significance.m .
