高斯光束的傅里叶变换，基于matlab的仿真(Gaussian beam Fourier transform, matlab simulation)

Image enhancement for gray sacle images

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.)

说明：  lpcc的基本算法。使用matlab实现(lpcc the basic algorithm. Implementation using matlab)

对一维信号采样并进行傅里叶变换画出频谱图。(Sampling and Fourier transform draw spectrum diagram of one-dimensional signal.)

OFDM传输系统基本Matlab仿真程序，信道模型为AWGN/多径瑞利信道，调制方式可选择QPSK/16QAM/64QAM(OFDM transmission system basically Matlab simulation program, channel model for AWGN/Multipath Rayleigh channel, selectable modulation QPSK/16QAM/64QAM)

可以用此代码信号实现频谱仿真，希望对大家有用(You can use this code to achieve spectrum signal simulation, we hope to be useful)
