基于matlab 来开发QR识别和译码程序，运用图像校正、二值化、边缘检测等各种图像处理方法实现条码的预处理，并进行QR码的解码和纠错算法，充分利用面向对象的方法，结合图像处理技术，完成了基于图像处理的QR码快速识别的解码系统。(Based on Matlab QR recognition and decoding procedures, the use of the image correction, binarization, edge detection, and other various image processing methods to achieve the pretreatment of the code, and a QR code decoding and error correction algorithm, the full use of the object-oriented approach, combined with image processing technology, based on the completion of image processing QR code decoding system to quickly identify.)

说明：  OFDM系统中，在没有频率偏差时，解调后的结果与原始数据一致，而存在频率偏差时，解调后的结果与原始数据差异较大，且频率偏差越大，解调结果与原始数据的差异就越大。(In OFDM system, when there is no frequency deviation, the demodulation result is consistent with the original data, while when there is frequency deviation, the demodulation result is significantly different from the original data, and the greater the frequency deviation is, the greater the difference between the demodulation result and the original data will be.)

说明：  经典的fastica算法，实现盲源分离，速度较快且效果较好(The classic FastICA algorithm can achieve blind source separation with fast speed and good effect)

This is a note talk about Block coding Technique for reduction PAPR.
