Accurately estimating aboveground dry biomass (ADB) is crucial. The ADB of rice has primarily been estimated using vegetation indices with several discrete bands; nevertheless, these cannot take advantage continuous bands available hyperspectral remote sensing. This study analyzed the quantitative relationship between canopy characteristic parameters (HCPs) and rice. Twenty HCPs were used, incl...

SUMMARY " Cognitive radio " and " software-defined radio " (SDR) are today an important consideration in major spectrum debates in the United States. The U.S. drafted its first SDR rules in 2001, and since has continued efforts to resolve potential regulatory concerns and facilitate the benefits of the technology. At the same time, Japan has had a very rich experience in the lab with SDR, with ...

The TREC Spoken Document Retrieval Track (SDR) and the Topic Detection and Tracking (TDT) project have annotated the same corpus with difference styles of relevance judgements, using differenct notions of topic. We compare the behavior of a topic tracking system using relevance judgements from TDT with that of the same system using relevance from the SDR in order to investigate the influence of...

Within the scope of the European policy for Intelligent Transport Systems (ITS), the PLATA-PROTON project proposes a multitechnology cooperative Advanced Driver Assistance System (ADAS), based on the integration of Software-Defined Radio (SDR) devices in vehicles. With the choice of significant road-safety related scenarios, V2V and V2I communications have been both implemented and simulated. T...

In wireless communications, particularly the military space, software-defined radio (SDR) is the goal. The basic concept of SDR is to position the digital-to-analog separation as close as possible to the antenna. This is accomplished by implementing many functions traditionally performed by analog circuits using reconfigurable digital circuits. Successfully implemented, this can deliver an obso...

This article describes the use of Software Defined Radio over the Software Controlled Radio in a cooperative wireless network in an OFDM based downlink scenario. The article argues that although the state of the art of SCR is considered superior with respect to implementation factors such as complexity, cost and efficiency, the SDR offers a degree of flexibility together with the use of coopera...

This paper describes the real-time software implementation of NTSC Analog TV on the Sandblaster SDR platform. The platform supports realtime execution of a number of communication protocols and multimedia applications, including: 802.11b, WCDMA, GSM, GPS, MPEG4, H.264 and others. Our implementation of analog TV runs in real-time on Sandblaster evaluation board and produces highquality visual ou...

This novel architecture supports various future eEnabled airplane applications based on RFID technology. As RFID readers and wireless communication equipment is installed on-board of airplanes, it has to support a manifold of different wireless communication standards. The flexibility offered by Software Defined Radio (SDR) plays here an essential role. The security solution concept identifies ...
