移動(dòng)ip書(shū)籍，很有用。
Third Generation (3G) mobile offers access to broadband multimedia services - and in the future most of these, even voice and video, will be IP-based. However 3G networks are not based on IP technologies, rather they are an evolution from existing 2G networks. Much work needs to be done to IP QoS and mobility protocols and architectures for them to be able to provide the functionality 3G requires.
Space-Time Processing for CDMA Mobile Communications.Written for research students and design engineers, this book addresses many basic questions related to the use of space-time processing in CDMA-based Third-generation systems
Already the industry standard for Python users, Programming
Python from
O Reilly just got even better. This Third edition has been updated to
reflect current best practices and
the abundance of changes introduced by the latest version of the
language, Python 2.5

After the successful global introduction during the past decade of the second generation (2G) digital
mobile communications systems, it seems that the Third generation (3G) Universal Mobile Communication
System (UMTS) has finally taken off, at least in some regions. The plethora of new services that
are expected to be offered by this system requires the development of new paradigms in the way scarce
radio resources should be managed. The Quality of Service (QoS) concept, which introduces in a natural
way the service differentiation and the possibility of adapting the resource consumption to the specific
service requirements, will open the door for the provision of advanced wireless services to the mass
market.
Introduction
Computer security is undeniably important, and as new vulnerabilities are discovered and
exploited, the perceived need for new security solutions grows. "Trusted computing"
initiatives propose to solve some of today s security problems through hardware changes
to the personal computer. Changing hardware design isn t inherently suspicious, but the
leading trusted computing proposals have a high cost: they provide security to users
while giving Third parties the power to enforce policies on users computers against the
users wishes -- they let others pressure you to hand some control over your PC to
someone else. This is a "feature" ready-made for abuse by software authors who want to
anticompetitively choke off rival software.
It needn t be this way: a straightforward change to the plans of trusted computing vendors
could leave the security benefits intact while ensuring that a PC owner s
