说明：  Bpsk在瑞利衰落信道下的仿真模型。simulink实现。可以通过仿真看到瑞利衰落信道对于bpsk性能的影响。并且可以比较rayleigh信道和AWGN信道下bpsk的性能。(Bpsk in Rayleigh fading channel simulation model. Simulink achieve. Simulation can see Rayleigh fading channels for BPSK performance impact. And to be compared Rayleigh Channel and AWGN under BPSK performance.)

对雷达方程的研究，输出功率与测量距离之间的关系(Radar equation, the relationship between the output power and measure the distance)

cluster validity measure and its applicatio

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.
