This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures). Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own. I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

Obtain the CDF plots of PAPR from an OFDM BPSK transmission specified per IEEE 802.11a specification Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely. Using a small script, the cumulative distribution of PAPR from each OFDM symbol, modulated by a random BPSK signal is obtained

NAME: u2440mon.c DESC: u2440mon entry point,menu,download HISTORY: Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X. Mar.27.2002:purnnamu: DMA is enabled. Apr.01.2002:purnnamu: isDownloadReady flag is added. Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop. So, isDownloadReady flag gets not needed - UART ch.1 can be selected for the console. Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1 Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.

GloptiPoly 3: moments, optimization and semidefinite programming. Gloptipoly 3 is intended to solve, or at least approximate, the Generalized Problem of Moments (GPM), an infinite-dimensional optimization problem which can be viewed as an extension of the classical problem of moments [8]. From a theoretical viewpoint, the GPM has developments and impact in various areas of mathematics such as algebra, Fourier analysis, functional analysis, operator theory, probability and statistics, to cite a few. In addition, and despite a rather simple and short formulation, the GPM has a large number of important applications in various fields such as optimization, probability, finance, control, signal processing, chemistry, cristallography, tomography, etc. For an account of various methodologies as well as some of potential applications, the interested reader is referred to [1, 2] and the nice collection of papers [5].

Der Aufbau eines kleinen Frequenzzä hers ist dank der heutigen Atmel AVR Controller oder aber auch der Mikrochip PIC Controller (um nur zwei zu nennen) relativ schnell und einfach aufzubauen. Dazu werden meist die internen Timer/Counter des Controllers benutzt. Der Counter wird durch das anliegende Signal am Takteingang hoch gezä hlt. Durch den Timer wird dann der Counter zu einen festgelegten Zeitpunkt stetig ausgelesen und zurückgesetzt. Nehmen wir mal an ein 20Hz TTL-Signal taktet den Counter so steht nun im Counterregister nach einer Sekunde der Wert 20. Dieser wird nur noch auf dem Display oder serielle Schnittstelle ausgegeben. Nach einer erfolgreichen Auktion bei einen einschlä gigen Internet Auktionshaus, erwarb ich einige 7Segment Anzeigen, hierfür musste ich mir etwas einfallen lassen. Heraus kam somit ein besagter kleiner preiswerter 50MHz Frequenzzä hler, den ich nicht vorenthalten will.
