Orthogonal Data Embedding for Binary Images in
Morphological Transform Domain-A High- Capacity Approach
ABSTRACT:
This paper proposes a data-hiding technique for binary images in morphological transform domain for authentication purpose. To achieve blind watermark extraction, it is difficult to use the detail coefficients directly as a location map to determine the data-hiding locations. Hence, we view flipping an edge pixel in binary images as shifting the edge location one pixel horizontally and vertically. Based on this observation, we pro ....etc

You can total your current semester courses and credits with our online GPA Calculator. The online GPA calculator is a tool to calculate grade point average based on a typical high school system. GPA is calculated by dividing the total amount of grade points earned by the total amount of credit hours attempted. We think you will find our GPA calculator both easy to use and helpful. Students can use the GPA calculator to determine their present high school, college, or graduate school grade point average, determine what their GPA is likely to be ....etc

Orthogonal Frequency Division Multiplexing (OFDM)

ABSTRACT
Orthogonal Frequency Division Multiplexing (OFDM) has recently gained a lot of attention and is a promising candidate for future wireless multimedia communications due to it is resistive to frequency-selective fading and its flexibility for handling multiple data rates for Fourth Generation (4G) wireless systems also it promises data rates up to 10Mbps. A variation of OFDM is Multi-Carrier CDMA (MC-CDMA), in which an OFDM technique and CDM ....etc

Orthogonal Frequency Division Multiplplexing

Multi Carrier Modulation is a technique for data transmission by dividing a high bit rate data stream is several parallel low bit ]rate data streams and using these low bit rate data streams to modulate several carriers. Multi Carrier Transmission has a lot of useful properties such as delay spread tolerance and spectrum efficiency that encourage their use in untethered broadband communications. OFDM is a multi carrier modulation technique with densely spaced sub carriers tha ....etc

Abstract:
Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user version. Multiple access is achieved in OFDMA by assigning subsets of subcarriers to individual users. This allows simultaneous low data rate transmission from several users, OFDM is sometimes referred to as discrete multi-tone modulation, instead of a single carrier being modulated, a large number of evenly spaced subcarriers are modulated using some m-ary of QAM. This is a spread-spectrum technique that increases the efficiency of data communications by increasin ....etc

Orthogonal Frequency Division Multiplexing


1. INTRODUCTION
1.1. Introduction:-
Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation techniques used in order to combat the frequency-selectivity of the transmission channels, achieving high data rate without inter symbol interference. The basic principle of OFDM is gaining a wide spread popularity within the wireless transmission community. Furthermore,
OFDM is one of the main techniques proposed to be employed in ....etc

The calculator is an extension of a mathematician and it has opened up new possibilities within mathematics. It is a machine though, and it is only capable of doing what it is programmed to do. Accordingly, this project aims to develop the internal programmed computational code in the form of a computer program that a scientific calculator could use to compute functions such as square root, the exponential, and sine functions.1 The idea of this project assumes that that the programmer has already developed the very basic addition, subtr ....etc
