OFDM通信系统性能仿真，包括PAPR抑制、同步算法、编码、上下变频、高斯信道建模等(OFDM communication system simulation, including the PAPR suppression, synchronization algorithm, coding, frequency up and down, Gaussian channel model)

Module Provides implementation of SURF Points to detect invariant features input image for robust image matching. It takes less time to detect features an image rather than SIFT

本实验程序用于计算信号的包络和包络信号的频谱（包络谱）。 算法采用了Hilbert变换计算包络( This experiment is used to calculate the envelope (envelope) of the envelope and envelope of the signal. The algorithm uses a Hilbert transform to compute the envelope)

GPS Global Positioning System for matlab ,

Matlab程序为清华大学胡广书版信号处理的上机习题答案(Matlab procedures for Qinghua University HU-book version of the signal processing on the answer machine Exercises)

The purpose of this Primer is to help you begin to use MATLAB. It is not intended to be a substitute for the online help facility or the MATLAB documentation (such as Getting Started with MATLAB, available in printed form and online). The Primer can best be used hands-on. You are encouraged to work at the computer as you read the Primer and freely experiment with the examples. This Primer, along with the online help facility, usually suffices for students in a class requiring the use of MATLAB.

This is an efficient implementation of the algorithm for calculating the universal image quality index proposed by Zhou Wang and Alan C. Bovik. Please refer to the paper "A Universal Image Quality Index" by Zhou Wang and Alan C. Bovik, published in IEEE Signal Processing Letters, 2001.

It is a novel fuzzy based sleep mode technique for WSN that turns off the ONUs (placed at the customer premises) when certain traffic conditions are verified. The objective is to achieve an improved energy efficiency without impacting too much the Quality of Service perceived by end-users. The whole operation is managed at the central Node and the length of the sleep time periods is computed employing a statistical method.
