Hilbert缝隙天线的频率可重构设计 (Hilbert slot antenna frequency reconfigurable design)

这是一个非常完整的pi/4dqpsk 调制解调的matlab仿真，给出了各个阶段的波形图，并且分析了在高斯信道下面的误码率，以及星座图和功率谱(This is a very complete matlab simulation of pi/4dqpsk modulation and demodulation. The waveform diagram of each stage is given, and the bit error rate under Gao Si channel, constellation diagram and power spectrum are analyzed.)

The JPEG compression scheme is divided into the following stages: 1. Transform the image into an optimal color space. 2. Adjust Aspect Ratio 16:9 3. Digitization Scheme 4:2:0. 4. Apply a Discrete Cosine Transform (DCT) to blocks of pixels, thus removing redundant image data. 5. Quantize each block of DCT coefficients using weighting functions optimized for the human eye. 6. Encode the resulting coefficients (image data) using a Huffman variable word-length algorithm to remove redundancies in the coefficients. 7. Byte Stuffing. 8. Header JFIF 9. JPG Data Store
