TravelingProblem

基于DCT的数字水印的Matlab仿真实现(Digital Watermarking Based on DCT of Matlab simulation)

说明：  PLL是一个锁相环模块，能得到波形的相角，从而实现同步信号的控制(PLL is a phase-locked loop module, waveform, phase angle, in order to achieve the control of the synchronization signal)

OFDMA上行链路的模拟程序，可能有一些小BUG(OFDMA uplink simulation program, there may be some small BUG)

单载波频域均衡中，信道是一个很关键的问题，信道估计的好坏也直接影响系统的性能，确定一个好的信道估计序列是至关重要的，chu 序列是一种很好的估计序列(Single-carrier frequency domain equalization, the channel is a very critical issue, good or bad channel estimation is also directly affect the performance of the system to determine a good channel estimation sequence is critical, chu sequence is a good estimate of the sequence)

使用矢量量化的方法进行说话人识别，用matlab编写 (Vector quantization method using speech recognition, written with matlab)

利用该matlab程序对近红外光谱进行MSC等预处理，很好用。(The use of near-infrared spectroscopy matlab program pretreated MSC so easy to use.)

General Embedded Quantization for Wavelet-Based Lossy Image Coding

用声卡输出的单边带信号源，SSB下边带信号，载波15KHz，输入声音带宽设为300~3.4KHz，SSB调制后输出带宽为11.6K~14.7KHz，可以给SSB解调器实验做信号源了。(Single-sideband signal with the sound output source, SSB below band signal, carrier 15KHz, enter the voice bandwidth set at 300 ~ 3.4KHz, SSB modulated output bandwidth 11.6K ~ 14.7KHz, you can do to the SSB demodulator source experiment the.)

说明：  如题，很简单的小工具，信噪比snr和均方mse的MATLAB代码。(As topic,a very simple tool, SNR and MSE MATLAB code.)
