Mobile devices, scalability & digital ecologies
2010 Edition, April 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Mobile handsets (phones) are expected to increase from the current 4.5B (billion) subscriptions to over 6B in 2013 and thus dwarf the numbers of PCs (e.g. desktop, laptop, netbook, etc.) that are expected to rise from the current 1.1B to 2B in 2015. But more importantly, data transmission...

Digital transmitter design for mobile devices
2013 Edition, Volume 51, October 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The advancement of the process technology, especially CMOS technology, has played a major role in the miniaturization of the mobile device as well as extending its battery life. As digital logic continues to shrink in size and increase in density, implementing RF/analog...

Image coding with rational spatial scalability
2006 Edition, September 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In the digital TV and mobile operators scene, there is an increasing demand for a wider scalability range when delivering content to heterogeneous client devices which have different screen sizes. Subband image coding with classical wavelet transform only provide dyadic...

Is the cloud the answer to scalability of ecologies? Using GAE to enable horizontal scalability
2011 Edition, May 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Digital Ecosystem (DE) paradigm is a holistic management/design/integration approach that is based on the notion of self-interested, self-managing, proactive and autonomous digital entities that evolve and self-organize. While a DE can be realized using different technologies (e.g...

Providing Digital Time Stamping Services to Mobile Devices
2003 Edition, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Technology evolution in wireless communication is enabling pervasive connectivity to Internet scale systems. In this scenario, security critical applications are being deployed over platforms which include mobile devices. It is thus key that security services be provided to...

On the scalability of data synchronization protocols for PDAs and mobile devices
2002 Edition, Volume 16, July 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Personal digital assistants and other mobile computing devices rely on synchronization protocols in order to maintain data consistency. These protocols operate in environments where network resources such as bandwidth, memory and processing power are limited. We examine a...

Mobile event-oriented digital ecosystem
2012 Edition, June 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Digital Ecosystem (DE) paradigm is a holistic management/design/integration approach that is based on the notion of self-interested, self-managing, proactive and autonomous digital entities that evolve and self-organize. This in turn leads to the emergence of complex,...

What's new in digital displays?
2008 Edition, Volume 14, July 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Flexible displays using plastic film substrates are key devices for ubiquitous and universal services of digital broadcasting because of their mobile characteristics, low-cost productivity, and flexibility of viewing style. Polymer organic light-emitting devices (POLEDs)...

Scalability of RF CMOS
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The scalability of advanced CMOS processes for RF applications is presented from a circuit design and system integration perspective. The impact of transistor scaling and advanced interconnects on active device performance and passive component quality is examined. Key...

Temporal video transcoding for Digital TV broadcasting
2012 Edition, September 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Mobile Digital TV environments demand flexible video compression like Scalable Video Coding (SVC) because of varying bandwidths and devices. Since existing infrastructures highly rely on H.264/AVC video compression, network providers could adapt the current H.264/AVC...
