Detection of Unknown Signals in a Fading Environment



INTRODUCTION
The energy detection is a common approach to
decide whether unknown signals exist in the
medium. The first step of the detector design
requires a model for the distribution of the noise
and the signal. It is reasonable to describe the noise
as a simple white Gaussian process. The signal
model has to be more complex to incorporate the
fading effects.

Abstract

A complexity reduction algorithm for an H.264 encoder is proposed. This comes at the cost of the number of increased macroblock modes and the complex mode decision procedure using the rate-distortion optimization . H.264 demands a high degree of computational complexity to be able to make use of the advantages of its new techniques. Experiment results in show that the proposed algorithm can reduce the encoding time by 29.67% on average and the rate-distortion comput ....etc

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.

• A FADE is a gradual increase or decrease in ....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
