Visual C++与Matlab混合编程实现语音识别(Visual C++ and Matlab programming hybrid speech recognition)

matlab模拟退火算法的TSP算法，并实现以求解得到最优。(matlab simulated annealing algorithm TSP algorithm and implementation.)

抽象类以及纯虚函数的相关笔记。Figure作为基类，派生出Circle，Square(Abstract classes and pure virtual functions related notes. Figure as a base class, derived Circle, Square)

基于matalab的信道自适应均衡技术研究(Matalab based channel adaptive equalization technology research)

说明：  信号调幅，对于输入的正弦信号进行模拟幅度调制、传输、解调(Signal amplitude, the input analog signal is a sinusoidal amplitude modulation, transmission, demodulates)

说明：  OFDM调制的的AWGN加瑞丽衰落信道，其它的我就不多说了(OFDM modulation of the AWGN Jiaruili fading channel, and others I do not talk a lot)

在数字信号的基带传输过程中，信息传输速率在满足香农公式的条件下还极大地受到码间干扰的限制(It is also limited by intersymbol interference when transmission speed of code accord with Shannon expressions in the course of baseband transmission of digital signal.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

LM算法的MATLAB实现。Levenberg-Marquardt算法是最优化算法中的一种。最优化是寻找使得函数值最小的参数向量。(LM algorithm in MATLAB. Levenberg-Marquardt algorithm is an optimization algorithm. Optimization is to find the minimum value makes the function parameter vector.)
