-Error-controlled coding techniques are used to detect and/or correct errors that occur in the message transmission in a digital communications system. Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools.

Description: The book can be used as a basis for one course, or a two course sequence, in digital communication. The following topics are covered: complex baseband representation of signals and noise (and its relation to modern transceiver
implementation) modulation (emphasizing linear modulation) demodulation
(starting from detection theory basics) communication over dispersive chan-
nels, including equalization and multicarrier modulation computation of performance benchmarks using information theory basics of modern coding strategies (including convolutional codes and turbo-like codes) and introduction to wireless communication. -The book can be used as a basis for one course, or a two course sequence, in digital communication.

Description: In this paper, we address a new unexplored problem
- what are the optimal patterns to achieve connected coverage in
wireless networks with directional antennas. As their name implies,
directional antennas can focus their transmission energy in
a certain direction. This feature leads to lower cross-interference
and larger communication distance. It has been shown that with
proper scheduling mechanisms, directional antennas may substantially
improve networking performance in wireless networks.
In this paper, we propose a set of optimal patterns to achieve
full coverage and global connectivity under two different antenna
models, i.e., the sector model and the knob model. We also
introduce with detailed analysis several fundamental theorems
and conjectures. Finally, we examine a more realistic sensor
model, where sensing range and communication range may both
vary randomly. Results show that our designed patterns work
well even in unstable and fickle physical environment. Platform: |

Description: Technology has become synonymous with communication because technology
has historically been the method by which communication to or by the general
population takes place. From the printing press to the telephone to radio and TV
broadcasting, technology has touched our lives by providing convenient ways for
a large population to communicate. Because the intertwining of technology and
communication is fundamental to our culture, the technology of communication
in a way defines our culture. Platform: |
