基于Matlab的八度音阶发音演奏程序，包括9个源文件，七个音阶，一个频率调制，一个完成结果(Matlab based on the pronunciation of playing octaves procedures, including nine source files, seven scale, a frequency modulation, the results of a completed)

这篇文章讲述基于相空间重构的模糊集用于复时间序列的暂态模式。文章详细说明关于时间序列的构建、说明暂态识别的概念、原理，优化函数的选择和优化结果等均有很好的步骤和完整实验结果。(This article describes the phase space reconstruction based on fuzzy sets for the transient model complex time series. Article details the construction of time series to illustrate the concept of transient identification, theory, optimal function of the selection and optimization results of the steps are very good and complete results.)

通过FIR滤波器的自适应调整，不断修正其系统函数，使其与未知系统的参数充分逼近，从而使误差最小，达到系统辨识的目的。 (Through the adaptive FIR filter, constantly modify the system function, with unknown system parameters to the full approach, so that error, and achieve the purpose of system identification.)

信号经过两个独立的信道传输，两个信道的信道复增益分别为 和 。 是独立同分布的复高斯随机变量，实部虚部独立、均值为0，实部虚部的方差都是1。采用某分集技术后输出的信噪比为 ，其中 是常数， 是在 之间均匀分布的随机变量。请就不同的 、 ，用仿真的方法画出 的累积分布函数。(signal after two independent Channel Tunnel, Channel 2 Channel Minute respectively, and gain. Independence is the same complex Gaussian distribution of random variables, is the imaginary part of the Department of independence, mean 0 and the real part of the imaginary part is a variance. Using a diversity of the output signal-to-noise, which is constant, is the uniform distribution between random variables. Please different, and simulation methods paint the cumulative distribution function.)

以动画的方式绘制出对数螺线 的图形，并用一个红色小球来跟踪螺线展开轨迹 以及积分过程(Graphics animation way to draw a logarithmic spiral, and a small red ball to keep track of the spiral to expand the track as well as integrating processes)

此程序主要演示通道间幅度误差对DBF旁瓣电平的影响。(This program is mainly to demonstrate of effect of channel amplitude errors on the sidelobes of DBF.)

The Bluetooth Voice model makes extensive use of frame based processing in Simulink, which can propagate large frames of samples at each execution step allowing for much faster simulation of digital systems.

通过输入相关参数，实现三阶累积量的求法。从而避免复杂的计算过程。(By input parameters, the third order cumulant method. To avoid complex calculation process. )

说明：  matlab实现模拟退火,程序实现很有效果(matlab implementation of simulated annealing, the program to achieve very effective)
