Software-defined radios and cognitive radios offer tremendous promise, while having great need for user authentication. Authenticating users is essential to ensuring authorized access and actions in private and secure communications networks. User authentication for software-defined radios

Abstract—After being the subject of speculation for many years, a software-defined radio receiver concept has emerged that is suit-able for mobile handsets. A key step forward is the realization that in mobile handsets, it is enough to receive one channel with any bandwidth, situated in any band

A software radio is a radio whose channel modulation waveforms are defined in software. A software radio receiver is an embedded platform that can support different communication standards. All the base-band processing is performed on a DSP. On the receiver side, the base-band processing

Abstract—Software Defined Radio (SDR) may provide flexible, upgradeable and longer lifetime radio equipment for the military and for civilian wireless communications infrastructure. SDR may also provide more flexible and possibly cheaper multi-standard-terminals for end users. It is also important

QPSK digital Modulation scheme and its implementation on FPGAs. The simulation of the system is made in MATLAB Simulink environment and System Generator, a tool used for FPGA design. This paper mainly focuses on the hardware realization of such scheme with a minimum area strategy for the universal mobile telecommunication system (UMTS), CDMA2000 and SDR applications. Hardware Co Simulation is designed using VHDL a hardware description language targeting a Virtex-5 device (XC5VLX50T-1ff1136) and is verified using MATLAB Simulink.
