ABSTRACT

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation and multiple access technique that has been explored for over 20 years. Only recently has it been finding its way into commercial communications systems. OFDM, or multitone modulation, is presently used in a number of commercial wired and wireless applications. In order for any mobile system to create a rich user experience, it must provide ubiquitous, fast and user-friendly connectivity. OFDM has several unique properties that make it especially well suited to handle ....etc

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.

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 ....etc

ABSTRACT:

OFDM
otherwise called orthogonal frequency division multiplexing is a modulation and a multiple access technique that can be applied to mobile communications.
OFDM or Multitone modulation as it is sometimes called is the basis for several commercial wireless applications. In OFDM the segments are according to frequency there by dividing the spectrum into a number of equally spaced tones, which are orthogonal with each other and carries a portion of user information ....etc

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

ABSTRACT :

Orthogonal frequency-division multiplexing is a popular method for high-data-rate wireless transmission. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-inp ....etc

ABSTRACT

Diversity combining receivers is the well-known technique used to combat fad-

employed in digital communication receivers including maximal-ratio combining, se-
lection combining and switched diversity. Among the combining methods, switched

Framework for power control in cellular systems
Abstract:
Efficiently sharing the spectrum resource is of paramount importance in wireless communication systems, in particular in Personal Communications where large numbers of wireless subscribers are to be served. Spectrum resource sharing involves protecting other users from excessive interference as well as making receivers more tolerant to this interference. Transmitter power control techniques fall into the first category. In this paper we describe the power control ....etc
