该报告详细介绍了Viterbi译码的方法，并分析了从卷积编码，调制，信道，解调，译码的详细步骤。(this article introduce the decoding way of convolutional code，and analysis the steps from coding ，modulating，channel，demodulating，and decoding。)

1． 了解FIR滤波器的原理及使用方法。2． 了解使用Matlab语言设计FIR滤波器的方法。了解DSP对FIR滤波器的设计及编程方法。(1.familiar with FIR. 2.familiar with using matlab design FIR 3.familiar with DSP program for FIR)

说明：  通过最大熵和自适应灰度阈值方法来对图像进行分割，可得到效果较好的分割图像(By maximum entropy and the adaptive threshold method of image segmentation, image segmentation can be obtained better)

Matlab code for sphit code and its use in compresion details

运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)
