Steganography LSB by 2 bits method Find and hide information in a image

说明：  DVBS2 system : transister + receiver

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

书本《Matlab数字信号处理与应用》上的matlab程序代码。很全面哦。(Book " Matlab Digital Signal Processing and Applications" on the matlab code. Oh, very comprehensive.)
