这是一个最基本的OFDM系统仿真，说明一个信号通过OFDM系统所产生信号对比(This is a basic OFDM system simulation, that a signal generated by the signal OFDM system comparison)

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.

小区初搜为GSM系统中的一个关键过程，本程序为GSM小区初搜过程查找并解广播控制信道bcch的matlab程序，输入数据由采样数据得到，在转换成所需格式后进行处理。若其中包含bcch,则输出找到信息，并通过解调译码等工作解其中信息信息。若没有，则发出错误信息。内付算法详细说明文档(Area early in the search for the GSM system, a key process, the procedures for the GSM cell and the beginning of search process to find solutions BCCH Broadcast Control Channel of matlab procedures, input data from the sampling data, converted into the desired format in the post-treatment. If one includes bcch, while the output to find information and work through the demodulation decoding information in which information solutions. If not, then send a wrong message. Pay the algorithm in detail within the document)
