matlab编程 包括课件和配套的程序源码 非常适合自学。(matlab programming, including courseware and supporting source code is very suitable for self-learning process.)

matlab标准遗传算法 优化函数为f=-(x-1)^2+4，其中，0<=x<=3(matlab)

基于自建数据库的音乐识别及检索软件 ； 利用Matlab开发软件, 通过抓取录入歌曲的音高(pitch tracking)绘出声音的频率变化并进行降噪和润滑（smoothing）处理 与数据库中歌曲的频率变化图比对，计算出相似度top10的歌曲并显示。 (Based on self-built of music recognition and retrieval software developed using Matlab software, change the pitch of a song by crawling entry (pitch tracking) plots the frequency of the sound and noise reduction and lubrication (smoothing) processing Frequency changes in the diagram songs than calculate the similarity top10 songs and displayed.)

用子空间分解法求出时延估计，这种方法具有较强的抗噪声性能(Calculated using subspace decomposition delay estimation, this method has strong anti-noise performance)

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)
