对lbfgsb优化算法的Matlab仿真( Matlab simulation of Optimization lbfgsb)

有关多媒体通信的课堂讲义，研究生教材，共六章,英文版本的(Class notes about multimedia communication, graduate teaching, a total of chapters, the English version of the)

对离散时间系进行了时域分析，包括一些基本的时域操作和分析(Department of discrete-time time-domain analysis, including some basic manipulation and analysis of time-domain)

设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)

说明：  载波相位调制解调4相PSK的比特误码率与理论差错概率原程序系统的性能分析与模拟 (Carrier phase 4 phase PSK modulation and demodulation bit error rate of the original program with the theoretical error probability analysis and simulation of system performance)

matlab比较简单的直方图阈值分割方法(Histogram thresholding)

matlab编写的数字签名言简意赅，相信一定会有人用到。(matlab digital signature prepared concise, I am sure someone will use.)

信号处理，有关自适应滤波器噪声抵消的应用；效果比较好，对学自适应滤波有一定的帮助。(Signal processing, the application of adaptive noise cancellation filter results were better for learning adaptive filter has some help.)

说明：  這是一個求數獨遊戲的m-file 在matlab的命令窗口 鍵入>> sudo7 或者run sudo7 的m-file 之後在 9x9 的方格內 填入 數獨的問題 按下 "計算是否有解" 的功能鍵 若不是存在多組的解，則可以 按下 "顯示結果" 的功能鍵， 也可以載入作者測試的"date1"或"date2" 但不可載入及修改"condition"(This is a Sudoku game for the m-file in matlab command window type>> sudo7 or run sudo7 the m-file after the box in the 9x9 Sudoku Fill in the question of pressing the calculate whether the solvability feature key if it were not for the existence of multiple solutions, you can press the show results of the function keys can also be included in the authors test date1 or date2 but not loading and modification of condition )
