DS-CDMA

用M语言编写的画多元数据平行坐标图代码，数据用的是一组蔬菜油（国际期刊）数据，写得不好，多指教。(By M art multi-language data parallel coordinates graph code, data used are a group of vegetable oils (International Journal) data, not well written, multi-index.)

注意：本程序中，每点击一次“增加亮度”，图像灰度提升16；每点击一次“降低亮度”，图像灰度降低16。(Note : This procedure, every click an "increase in brightness," gray upgrade 16; Click on each of a "lower brightness," gray lower 16.)

2D-DCT 压缩图像后，通过QPSK,AWGN信道编码传输后，IDCT解压缩回原始图像，适用于任何图像(Using DCT to compress the orginal image, I use zigzag program, quantization, dct compression, then change the vector to bineary bit to pass through the QPSK channel. And from the binary array, I use IDCT to reconstructe the orignial image. working perfectly.)
