A software defined radio (SDR) is a modern radio communication system that can be reconfigured on-the-fly. In this paper, we describe a project on introducing SDR to the Bachelor of Wireless Engineering (BWE) curriculum at Auburn University. Our efforts consist of three intertwined thrusts: (i) We offer well-defined SDR senior design projects, as well as research projects for students supported...
National Aeronautics and Space Administration (NASA) has developed a space-qualified, reprogrammable, Ka-band Software Defined Radio (SDR) to be utilized as part of an onorbit, reconfigurable testbed. The testbed will operate on the truss of the International Space Station beginning in late 2012. Three unique SDRs comprise the testbed, and each radio is compliant to the Space Telecommunications...
Human short-chain dehydrogenases/reductases (SDRs) protein family has been the subject of recent studies for its critical role in human metabolism. Studies also found that single nucleotide polymorphisms of the SDR protein family were responsible for a variety of genetic diseases, including type II diabetes. This study reports the effect of sequence variation on the structural and functional in...
OBJECTIVE This study examined the comorbidity of obsessive-compulsive disorder (OCD) with major depressive disorder (MDD) in a family study of OCD with pediatric probands. METHOD This study assessed the lifetime prevalence of MDD in 141 first-degree relatives (FDR) and 452 second-degree relatives (SDR) of pediatric probands with OCD and healthy controls, and identified variables associated wi...
AIM To assess the long-term outcome and adverse events of selective dorsal rhizotomy (SDR) in children with spastic cerebral palsy (CP). METHOD Studies were selected based on the following inclusion criteria: children with CP that underwent SDR with a follow-up period of at least 5 years. The following databases were searched: MEDLINE, Web of Science, Embase, PEDro, and the Cochrane library. ...
Infection of host tissues by Staphylococcus aureus and S. epidermidis requires an unusual family of staphylococcal adhesive proteins that contain long stretches of serine-aspartate dipeptide-repeats (SDR). The prototype member of this family is clumping factor A (ClfA), a key virulence factor that mediates adhesion to host tissues by binding to extracellular matrix proteins such as fibrinogen. ...
BACKGROUND Selective dorsal rhizotomy (SDR) is often recommended for children with spastic paraparesis and cerebral palsy. SDR reduces spasticity in the lower extremities for these children with spastic paraplegia. However, SDR is infrequently recommended for adults with spasticity. Spastic diplegia in adult patients can be due to stroke, brain or spinal cord injury from trauma, infection, toxi...
A Software defined radio (SDR) defines the transmitted waveforms and demodulates the received waveforms. SDR is an interdisciplinary technology involving a combination of hardware and software technologies where some or all of the physical layer functionality are programmable. Re-configurable platform of SDR device hosts several software components to provide users with functional services. A u...
Recently, Cognitive Radio has been proposed as a promising technology to improve spectrum utilization. A highly flexible SDR (Software defined Radio) system needs to configure each of its blocks to give optimum performance over the available bandwidth. Present work discusses an approach for software defined adaptive coder yielding minimum BER (Bit error rate) for emergency services over cogniti...
The use of mobile telephony has shown a spectacular growth in the last 10 years. A side effect of this rapid growth is an excess of mobile system standards. Therefore, the Software-Defined-Radio (SDR) concept is emerging as a potential pragmatic solution: it aims to build flexible radio systems, which are multi-service, multi-standard, multiband, re-configurable and re-programmable, by software...
