BER-SNR curve of A-PSK modulator

monto carlo optimization code

和Huffman-Tree一样，Shannon-Fano coding也是用一棵二叉树对字符进行编码。但在实际操作中呢，Shannon-Fano却没有大用处，这是由于它与Huffman coding相比，编码效率较低的结果（或者说香农-范诺算法的编码平均码字较大）。(And Huffman-Tree, like, Shannon-Fano coding is using a binary character coding. However, in practice it, Shannon-Fano, but not much use, since it is compared with the Huffman coding, coding efficiency is the result of a lower (or Shannon- Fano coding algorithm larger average code word).)

实现了曲线拟合，关于客车燃油经济性的曲线(vc++ achieve numerical simulation with the approximation method of calculating least-squares curve fitting )

说明：  升压DC-DC变换器BOOSt的PWM闭环控制的 simulink仿真(Step-up DC-DC converter BOOSt the PWM control loop simulation simulink)

声源定位中，提高时延估计精度的一种方法，即通过将原始信号取其立方后在做相关，得到的峰值更加尖锐。(Sound localization, the increase in the accuracy of time delay estimation method, whichever is the original signal through the cube after doing related to the peak obtained is more acute.)

主要是用于提取超声导波的时域特征，例如偏度参数、峰度系数、形状系数、离散系数等等(Time Domain Characteristics for Extracting Ultrasound Guided Waves)

雷达的线性调频信号matlab仿真模拟，适合雷达信号处理初学者，程序已经过验证。(The linear FM signal matlab radar simulation, is suitable for beginners of radar signal processing, the program has been verified.)

说明：  产生BPSK基带数字信号的时域波形。其中基带数字信号的传输速率以及每个码元周期内载波的周期数可以设置。(To generate the time-domain wave for BPSK. And the transmitting rate and the frequency of the carrier can both be set in the program.)

In this paper, we try to find out the efficiency of K-means algorithm with respect to different distance measures
