INTRODUCTION… Communication has existed since the beginning of human beings‚ but it was not until the 20th century that people began to study the process. As communication technologies developed‚ so did the theories. Before becoming simply communication‚ or communication studies‚ the discipline was formed from three other major studies: psychology‚ sociology‚ and anthropology. Psychology is the study of human behaviour‚ Sociology is the study of society and social process‚ and anthropology

Performance Analysis of OFDM Systems using Cooperative Diversity Techniques Abstrac t: Cooperative Diversity has been widely used in wireless network‚ and Orthogonal frequency division multiplexing (OFDM) is a key technique of multi-carrier transmission to meet high data rate requirement of wireless communication. The aim of this project is to combine the technology of OFDM with cooperative diversity techniques. The simulation will be done in MATLAB. The performance of the system will be compared

1168 Abstract—In this paper‚ we address the problem of privacy protection in video surveillance. We introduce two efficient approaches to conceal regions of interest (ROIs) based on transform-domain or codestream-domain scrambling. In the first technique‚ the sign of selected transform coefficients is pseudorandomly flipped during encoding. In the second method‚ some bits of the codestream are pseudorandomly inverted. We address more specifically the cases of MPEG-4 as it is today the prevailing standard

Chapter 1 INTRODUCTION Computerization is a control system that manages the process in industrial workplace. It reduces human errors and processing time‚ thus it can boost productivity and results into high quality of product produce. In an information system‚ computerization is concerned about interrelating different but interdependent transactions. This can result in a system with well-integrated processes that can perform much faster and more accurate than a manual system. Enrollment is

external modulators which modulate the light by changing its refractive index through the given input electrical signal. In the digital optical fiber communication system‚ the input electrical signal is in the form of coded digital pulses from the encoder and these electric pulses modulate the intensity of the light from the laser diode or LED and convert them into optical pulses. In the receiver stage‚ the photo detector like avalanche photodiode (APD) or positive-intrinsic-negative (PIN) diode converts
