AUDIO FADING


BACKGROUND
The Planet written by Gustav Holst between 1914 and 1916, was the first piece of music in that era to have an audio fading. We use this technique because the imagination knew no difference between sound and silence. Fade-in and fade-out are cinematic devices that begin and end scene. The term 'fade-out' itself is of cinematic origin, appearing in print around 1918.

THEORY
A FADE is a gradual increase or decrease in the level of an audio sign ....etc

Abstract

Wireless technology has become the most exciting area in telecommunication and networking. The rapid growth of mobile telephone use, various satellite services, and now the wireless Internet are generating tremendous changes in telecommunications and networking. Wireless is convenient and often less expensive to deploy than fixed service, but wireless is not perfect. There are limitations, political and technical difficulties that may ultimately prevent wireless technologies from reaching their full potential. Regardless of t ....etc

Moments and Channel Capacity of Single and
Dual-Branch Receivers Over Weibull Fading Channels



ABSTRACT

Diversity combining receivers is the well-known technique used to combat fad-
ing and improve system performance. There are several diversity reception methods
employed in digital communication receivers including maximal-ratio combining, se-
lection combining and switched diversity. Among the combining methods, switched
diversity offers one of the least complexity solution for fading mitigation and ....etc

Introduction

OFDM: a form of MultiCarrier Modulation.
Different symbols are transmitted over different subcarriers
Spectra overlap, but signals are orthogonal.
Example: Rectangular waveform -> Sinc spectrum

Performance analysis of channel estimation and adaptive equalization in slow fading channelPresented By:
Zhifeng Chen, Electrical and Computer Engineering, University of Florida
ABSTRACT
In our project, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, we test the effec ....etc

PERFORMANCE ANALYSIS OF WIDEBAND CDMA SYSTEMS IN A LOGNORMAL FADING CHANNEL

ABSTRACT

In this letter, the performance of a wideband CDMA system in the presence of Lognormal fading is studied. The wideband CDMA system, modeled using Gaussian Approximation is analyzed on a slow fading Lognormal channel which fades the amplitude of the transmitted signal according to the Lognormal Distr ....etc

A Theory of Anharmonic Lattice Statics for Analysis of Defective Crystals

In this topic we present a general theory of anharmonic lattice statics for analysis of defective complex lattices. This theory differs from the classical treatments of lattice statics in that it does not rely on knowledge of force constants for a limited number of nearest neighbor interactions. Instead, the only thing needed as input is an interatomic potential that models the interaction of atoms this theory takes into account the fact that close to defects force con ....etc
