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 us

信道编码和信道解码的程序,用于matlab的仿真的只用,可用于教学-Channel coding and channel decoding procedures, for the simulation of the matlab, only can be used for teaching
