Signal Processing in Genomics [From The Guest Editors]

Genomic signal processing has been defined as the analysis, processing, and use of genomic signals for gaining biological knowledge and the translation of that knowledge into systems-based applications.     

Bootstrap Methods in Signal Processing [From the Guest Editors]

The bootstrap does with a computer what the experimenter would do in practice if it were possible: they would repeat the experiment. The seven articles in this special section on bootstrap methods in signal processing are summarized here.     

Game theory in signal processing and communications [From the Guest Editors]

Game theory is a branch of mathematics aimed at the modeling and understanding of resource conflict problems. Essentially, the theory splits into two branches: noncooperative and cooperative game theory. The distinction between the two is whether or not the players in the game can make joint decisions regarding the choice of strategy. Noncooperative game theory is closely connected to minimax optimization and typically results in the study of various equilibria, most notably the Nash equilibrium. Cooperative game theory examines how strictly rational (selfish) actors can benefit from voluntary cooperation by reaching bargaining agreements. Another distinction is between static and dynamic game theory, where the latter can be viewed as a combination of game theory and optimal control. In general, the theory provides a structured approach to many important problems arising in signal processing and communications, notably resource allocation and robust transceiver optimization. Recent applications also occur in other emerging fields, such as cognitive radio, spectrum sharing, and in multihop-sensor and adhoc networks.     

Compressive Sampling [From the Guest Editors]

The ten articles in this special section provide the reader with specific insights into the basic theory, capabilities, and limitations of compressed sensing (CS). The papers are summarized here.     

Digital forensics [From the Guest Editors]

Today we find ourselves in a digital world, where most information is created, captured, transmitted, stored, and processed in digital form. Digital information permeates every aspect of our daily lives. Although representing information in digital form has many compelling technical and economic advantages, it has led to new issues and significant challenges when performing forensics analysis of digital evidence.     

Resource-Constrained Signal Processing, Communications, and Networking [From the Guest Editors]

To achieve the efficient use of the two principal resources of energy and radio spectrum, wireless systems and networks should be distributed, cooperative, and opportunistic.     

Signal processing: A view of the future, Part 1 [Exploratory DSP]

Yogi Berra, the famous baseball catcher, is reported to have said, "It's tough to make predictions, especially about the future." My rejoinder to that is that making predictions isn't hard at all. It's just tough to make ones that turn out to be right. With these ground rules established, we will try to predict the future of signal processing, with the intent of being able to use those predictions to do some intelligent planning.     

IPTV systems, standards, and architectures: Part I [Guest Editorial]

The four articles in Part 1 of this Feature Topic examine IPTV systems, standards, and architectures. The articles are summarized here.     

Teach-ware: Signal processing resources at connexions [Best of the Web]

In this issue, "Best of the Web" presents signal processing education resources available at Connexions (http://cnx.org). Connexions is a platform and environment for scholars to collaboratively develop and rapidly publish educational materials on the Web. It is based on a new approach to education that seeks to provide a place where everyone in the world can freely share knowledge, and it provides equal access to all people via tools that permit everyone ranging from university professors to school children to post and update knowledge in one place.     

Modeling and simulation: a practical guide for network designers and developers - [Guest editorial]

Modeling and simulation (M&S) is a critical element in the design, development, and test and evaluation (T&E) of any network product or solution. This feature topic features seven articles that present practical information such as current best practices, tools, and techniques.
