The role of radio in the communication systems have been extended from simple radio to mobile communications and beyond. Minimization or the replacement of hardware in communication technology through software has been resulted in the birth of a new technology, widely known as Software Defined Radio (SDR). This paper deals with the development of SDR to transfer information from one place to an...

Previously, we showed caveolae contain a population of protein kinase Calpha (PKCalpha) that appears to regulate membrane invagination. We now report that multiple PKC isoenzymes are enriched in caveolae of unstimulated fibroblasts. To understand the mechanism of PKC targeting, we prepared caveolae lacking PKCalpha and measured the interaction of recombinant PKCalpha with these membranes. PKCal...

Recently, a new approach for isolation of open faults in integrated circuits (ICs) was developed. It is based on mapping the radio-frequency (RF) magnetic field produced by the defective part fed with RF probing current, giving the name to Space Domain Reflectometry (SDR). SDR is a noncontact and nondestructive technique to localize open defects in package substrates, interconnections and semic...

A Software Defined Radio (SDR) is a radio receiver and/or transmitter, whose characteristics can to a large extent be defined by software. Thus, an SDR can receive and/or transmit a wide variety of signals, supporting many different standards. In our research, we currently focus on a demonstrator that is able to receive both Bluetooth and HiperLAN/2. This helps us to identify problems associate...

Software Defined Radio (SDR) and Cognitive Radio (CR) are fast technologies, which can be used to reduce the spectrum shortage problem. The modern software defined radio has been called the heart of a cognitive radio. The applications executing on the radio differentiate a cognitive radio from a software-defined radio. Additional hardware in the form of sensors and actuators increases the more ...

Software Defined Radio (SDR) requires a reliable, fast and flexible method to chain parametrisable algorithms. Communicating Sequential Processes (CSP) is a design methodology, which offers exactly these properties. This paper explores the idea of using a Java implementation of CSP (JCSP) to model a flexible algorithm chain for Software Defined Radio. JCSP offers the opportunity to distribute a...

Security in a communications system is the attribute that ensures that authorized traffic content is accurately delivered only to intended recipients and that use of system resources is accurately recorded. Introduction of RF links in mobile wireless introduces security considerations beyond those of wireline telephony because interception of the signal cannot be prevented. Implementation of ra...

Configuration of plasma reactors influences the generation of active species including the energized electrons, active radicals and the distribution of active species in reactor, and thus influences the removal efficiency of pollutants. Oxidation efficiency of elemental mercury (Hg) in two different DBD plasma reactors was studied in this paper. One plasma reactor is a surface discharge reactor...

Data distribution and access are major issues in space sciences as they influence the degree of data exploitation. The project “Space-Data Routers” (SDR) has the aim of allowing space agencies, academic institutes and research centres to share space data generated by single or multiple missions, in an efficient, secure and automated manner. The approach of SDR relies on space internetworking – ...
