. Recen t decades have marked by revolutionary changes, including the emergence of software-defined radio equipment (SDR). However, there is virtually no training in this area, which does not allow for the full realization of the benefits of new, more

Software-defined radio-based HF doppler receiving system
High-frequency Doppler (HFD) sounding is one of the major remote sensing techniques used for monitoring the ionosphere. Conventional systems for HFDs mainly utilize analog circuits.

Software Defined Radio—Guest Editorial [PDF]
Cognitive Radio (CR) is under intensive investigation since Joseph Mitola III published his doctoral dissertation in 2000. It is common understanding that Software Defined Radio (SDR) is the enabling technology for CR. A CR is an SDR that additionally senses its environment, tracks changes, and reacts upon its findings.

An architecture for software defined cognitive radio [PDF]
As we move forward towards the next generation of wireless protocols, the push for a better radio physical layer is ever increasing. Conventional radio architectures are limited to narrow operating regions and fails to adapt with changing technology.

Dynamic reconfiguration technologies based on FPGA in software defined radio system
Partial Reconfiguration (PR) is a method for Field Programmable Gate Array (FPGA) designs which allows multiple applications to time-share a portion of an FPGA while the rest of the device continues to operate unaffected.

Experimental Validation of an SDR-Based Direction of Arrival Estimation Testbed
Advanced mobile communication standards of the fifth and subsequent generations widely use beamforming technology. While many publications on this topic rely on simulation tools, some work has been dedicated to experimental testing using software-defined

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Software-Defined Radio—Basics and Evolution to Cognitive Radio
We provide a brief overview over the development of software-defined or reconfigurable radio systems. The need for software-defined radios is underlined and the most important notions used for such reconfigurable transceivers are thoroughly defined.

A software defined radio testbed implementation
We report on the implementation of a software defined radio (SDR) based on state-of-the-art digital signal processors (DSPs), which are linked serially to PCs.
