基于16APSK调制解调传输系统的仿真 16APSK调制技术有较高的数据传输速率，但是它的误码率也相对较高。(16APSK modem-based transmission system simulation 16APSK modulation technique for a higher data transfer rate, but its relatively high error rate.)

说明：  双有源全桥DC-DC变换器双重移相MATLAB仿真(Matlab simulation of double active full bridge double phase shifting)

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.
