NLmeansfilter
non local mean filter
commande example
I =mat2gray(imread( eight.tif ))
mn= 0
vr= 0.02
J = imnoise(I, gaussian ,mn,vr) add noise
output=NLmeansfilter3(J,7,3,0.1)

摘要:正交频分复用(OFDM)是第四代移动通信的核心技术。该文首先简要介绍了OFDM基本原理,重点研究了理想同步情
况下,保护时隙(CP)和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系
统模型的基础上,用MATLAB语言实现了整个系统的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,保
护时隙、信道估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。
(O FDM is the key techno logy of 4G in the field of mobile comm unication.In this article O FDM

programming-in-matlab-2
This tutorial is intended for those who want to learn basics of MATLAB programming language.
Even with a limited knowledge of this language a beginning programmer can write his/her own
computer code for solving problems that are complex enough to be solved by other means.
Numerous examples included in this text should help a reader to learn quickly basic programming
tools of this language. Topics discussed include the m-files, inline functions, control flow,
relational and logical operators, strings, cell arrays, rounding numbers to integers and MATLAB
graphics.
