Software Defined Radio (SDR) is a growing technology that allows radio communication to become interoperable. SDR can lower the cost for a particular hardware radio to commu- nicate with another radio that uses a different ...

This thesis examines the high peak-to-average-power ratio (PAPR) problem of OFDM and other spectrally-efficient multicarrier modulation schemes, specifically their stringent requirements for highly linear, power-inefficient ...

The Software Communications Architecture (SCA) is a standard for software defined radios (SDR) designed in part to promote code reuse for long-term development. With the emergence of adaptive/cognitive radios, new SDRs ...

Software defined radio (SDR) is a rapidly developing field enabled by continuing improvements in digital electronics. Software defined radio has been used extensively in communication systems due to its flexibility and ...

With the growing interest in software defined radios (SDRs), cognitive radios, the Joint Tactical Radio System (JTRS), and the Software Communication Architecture (SCA) comes the need for a rapid prototyping approach to ...

In this thesis, two different cases of hybrid IEEE 802.15.4 PHY (Physical Layer) implementation are explored. The first case is an FPGA implementation of IEEE 802.15.4 PHY on the Xilinx Spartan-3A DSP FPGA of USRP N210. ...

The rapid rise in computational performance offered by computer systems has greatly increased the number of practical software defined radio applications. The addition of FPGAs to these flexible systems has resulted in ...

Element CXI's Elemental Computing Array (ECA) delivers faster reconfiguration time and higher computational density than Field Programmable Gate Arrays (FPGAs) with similar computational power. It provides higher computational ...

Software Defined Radios are computer based systems that emulate the behavior of traditional radio systems by processing digitized radio signals. A SDR replaces the traditional fixed hardware radio with a system that may ...

Development of Cognitive Radio (CR) applications, which rely on a radio's ability to adapt intelligently to it's spectral surroundings will soon make the all important technological jump from research interest to systems ...
