Deployment in dynamic environments
Information and communication technologies are moving towards a new stage where applications will be dynamically deployed, uninstalled, updated and (re)configured. Several approaches have been followed with the goal of creating a fully automated and context-aware deployment system. Ideally, this system should be capable of handling the dynamics of this new situation, without losing sight of oth...
متن کاملComparative Study of PLL, DDS and DDS-based PLL Synthesis Techniques for Communication System
The phase locked loop(PLL) has been widely used in wireless communication systems due to the high frequency resolution and the short locking time. The Direct Digital Synthesis(DDS) is also an emerging and maturing signal generation technology. But another advanced technique in which, DDS signal is mixed with the voltage-control oscillator output in the PLL feedback path. This solution helps in ...
متن کاملDDS Based on Pipelined CORDIC Algorithm with Communication System
– The theoretical analysis gives an overview of the functioning of DDS, especially with respect to noise and spurs. Different spur reduction techniques are studied in detail. Four ICs, which were the circuit implementations of the DDS, were designed. One programmable logic device implementation of the CORDIC based quadrature amplitude modulation (QAM) modulator was designed with a separate D/A ...
متن کاملAutomatic Payload Deployment System
The ability to precisely emplace stand-alone payloads in hostile territory has long been on the wish list of US warfighters. This type of activity is one of the main functions of special operation forces, often conducted at great danger. Such risk can be mitigated by transitioning the manual placement of payloads over to an automated placement mechanism by the use of the Automatic Payload Deplo...
متن کاملSIG-DDS: a Grid-based Remote Sensing Data Distribution System
Data distribution is one of the most important steps for the remote sensing applications; it depends on the Remote Sensing Data Distribution System (RS-DDS). The conventional RS-DDS such as GCMD Mapserver [1] or CEOP [2] often provides a web based user interface and supports little data types only. Although the WCS [3]/WFS [4]/WMS [5] purposed by OGC try to make it possible for applications to ...
