第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)

线性系统理论中对线性系统的可加性齐次性的验证仿真(Linear system theory of linear systems can be added to the homogeneity of the validation of simulation)

该文件是学习matlab的经典教材，国内无法找到，本人从国外所得。(this book is the classical textbook for matlab.it is easy to learn and grasp by matlab engineers.)

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.
