多重分形去趋势交叉相关性分析DCCA,以及MF-DXA等程序代码，希望对大家有帮助(Multifractal cross correlation analysis of DCCA, and program code such as mm-dxa, hope to be helpful)

illustrates the improvement in BER performance when using log-likelihood instead of hard decision demodulation in a convolutionally coded communication link

介绍了算术编码的MATLAB程序，对初学者有帮助(Introduces MATLAB arithmetic coding procedures, to help beginners)

计算了贝塞尔函数的一阶导数的零点。 更新BessDerivZerosBisect.m这些变化： 1。允许对m= 0 2。允许用户指定特定的m和k值理想。 3。允许公差输入参数 4。使用一个表的查找能为m和k的小值接近初始化 5。添加错误检查 6。计算衍生w.r.t.以X而不是w.r.t.米（虽然老方法的工作也。）(Calculates the zeros of the first derivatives of Bessel function. Updates BessDerivZerosBisect.m with these changes: 1. Allows for m = 0 2. Allow the user to specify the particular m and k values desired. 3. Allows for a tolerance input parameter 4. Uses a table look-up to get closer initializations for small values of m and k. 5. Adds error checking 6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

广义预测控制是一种最具代表性的预测控制算法之一，本文通过对广义预测控制的稳定性、鲁棒性和实时性分析，得知它控制方程复杂、计算量过大、不利于实时控制。为此，广义预测控制算法，然后进行参数选择的研究，并针对冷连轧机张力系统进行了仿真，最后介绍了广义预测控制算法的其它改进方法。(Generalized predictive control is one of the most representative predictive control algorithms. This paper analysis the stability, robustness and real-time, But it has lots of calculations and unfavorable real-time. So this paper gives the algorithm of based on BP neural network of generalized predictive control. Then it analysis the system and the parameter selection, do some simulations to the cold continuous rolling machine tension system.)
