I have learn some of the codes for 4g.now I am in need to refer some codes related to my project

matlab资料汇总，内含有基本使用手册以及详细的进阶过程，适合初学者以及放在手边随时使用(matlab data collected, as well as a detailed manual contains basic advanced course is suitable for beginners as well as at hand ready for use)

说明：  simulink的PMSM svpwm模型。(simulink model of the PMSM svpwm.)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

三相异步电机的simlink仿真模型，可直接运行(Simlink simulation model of three-phase asynchronous motors can be run directly)

多小波中应用最多的就是DGHM多小波，该多小波有很好的去噪效果。(Multiwavelet Medium is the most widely used DGHM multiwavelet, the multiwavelet denoising has very good effect.)
