matlab学习手册是里面内容介绍的很详细，是学习MATLAB很好的学习资料。(matlab manual is inside the content of the study described in great detail, learning MATLAB is a very good learning materials.)

（1） 使用录音软件或者Matlab函数，分别采集一段浊音和清音语音信号（是你自己说的，如：a，o，s等），采样率为8KHz，量化精度为16比特线性码，存在自己指定的目录下，例如D盘根目录下叫sound的文件夹中，录音文件名为yourfilename_a.wav，yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。 （2） 根据语音信号的短时平稳特性，分析帧长取30ms（或10ms～50ms）； （3） 利用上述基音提取的三种方法（任选两种方法）的编程流程图（图1、图2和图3）编制浊音语音基音提取的matlab程序，上机调试给出相应波形，并根据图形，分析计算出基音周期。所用公式为： (1.5) 其中 是基音脉冲处所对应的位置， 是抽样频率， 是基音周期。 （4） 将语音信号换为清音语音，运行程序，与浊音语音的运行结果进行比较，并得出结论。 ( voice signal processing)

该程序用于生成一个线性调频信号（即chirp 信号），并对该信号进行压缩，显示结果图(to generate one chirp signal and then compress)

The Interleaved Frequency Division Multiple Ac- cess (IFDMA) scheme is based on compression, repetition and subsequent user dependent frequency shift of a modulated signal. Multiple access is enabled by the assignment of overlapping but mutually orthogonal subcarriers to each user. In this paper it is shown that IFDMA can be regarded as unitary precoded OFDMA with interleaved subcarriers. On the other hand, IFDMA is shown to be a CDMA variant with frequency domain orthogonal signature sequences and chip interleaving. Thus, it combines the advantages of single and multi carrier transmission such as low peak to average power ratio, orthogonality of the signals of different users even for transmission over a time dispersive channel and low complexity. Simulation results show the good performance of coded IFDMA transmission over a mobile radio channel for different data rates.
