典型宽带信号处理方法 csm_liu

说明：  基于MATLAB的OFDM信道估计算法，使用了PN序列作为导频，两种导频处信道估计处理方法，中间特别加入了相位估计处理(MATLAB-based channel estimation algorithm for OFDM using PN sequence as a pilot and two pilot channel estimation Department treatment methods, particularly the middle to join the treatment phase estimation)

A星算法实现路径规划动画演示 带gui界面(A star path planning with GUI)

双音多频 DTMF（Dual Tone Multi Frequency），双音多频，由高频群和低频群组成，高低频群各包含4个频率。(Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center. The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone. It was developed by Western Electric and first used by the Bell System in commerce, using that name as a registered trademark. DTMF is standardized by ITU-T Recommendation Q.23. It is also known in the UK as MF4.)

基于MATLAB搭建的超奈奎斯特（FTN）仿真系统(Based on Super Nyquist (FTN) MATLAB simulation system built)

说明：  用于混合动力汽车动力性经济性仿真，用simulink创建的模型(For hybrid vehicle dynamic simulation)

说明：  主要包含BPSK信号产生，成形滤波，调制，加噪，下变频，解调(It mainly includes BPSK signal generation, shaping filtering, modulation, noise adding, down conversion and demodulation)

说明：  一种新的图像去噪算法的matlab实现，效果比较好，运行速度较慢(A new image denoising algorithm matlab implementation, the effect is better, the running speed is slower.)

涉及12种copula的估计，以及模型的比较(Estimates of 12 kinds of copula, and comparison of the models)

伺服驱动器的电子凸轮功能，代替机械凸轮，应用广泛(Servo drive electronic cam function, instead of mechanical cams, widely)

说明：  GPS信号频谱，matlab语言，里面有CA码和P码的子文件，最后将各信号频谱画出来。(GPS signal spectrum, MATLAB language, there are ca code and P code sub file, finally the signal spectrum will be drawn.)
