fast convolution

本人改进的关于自适应分割方法，结合了大津法获得的阈值作为初始阈值，可以提高运行速度和分割效果(I improved on the adaptive segmentation method that combines the Otsu threshold obtained as the initial threshold, can improve speed and segmentation results)

这可是有关通信方面的MATLAB非常好的资料，而且很权威，是我们学习的号东西，里面有关通信方面的M文件十分齐全(This is related to communications MATLAB very good information, and are the authority, is something we can learn its inside on the communications papers are full of M)

通过仿真和分析对比SCFDMA的性能和算法。This is a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE. For information on SC-FDMA, go to SC-FDMA resource website at http://hgmyung.googlepages.com/scfdma. If you have any question, comment, or feedback, please visit the SC-FDMA discussion forum at http://scfdma.freeforums.org/ and leave your comment.(This is a very simple baseband simulator for SC-FDMA system.
