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 softwaredefined radios is underlined and the most important notions used for such reconfigurable transceivers are thoroughly defined. The role of standards in radio development is emphasized and the usage of transmission mode parameters in the construction of software-defined radio...
متن کاملFlexible Analog Front Ends of Reconfigurable Radios Based on Sampling and Reconstruction with Internal Filtering
Bandpass sampling, reconstruction, and antialiasing filtering in analog front ends potentially provide the best performance of software defined radios. However, conventional techniques used for these procedures limit reconfigurability and adaptivity of the radios, complicate integrated circuit implementation, and preclude achieving potential performance. Novel sampling and reconstruction techni...
متن کاملCognitive Radios and Cognitive Networks: A short Introduction
Radio spectrum is the most valuable resource in wireless communication. The cognitive radio and cognitive based networking are transforming the static spectrum allocation based communication systems in to dynamic spectrum allocation. Cognitive radios are intelligent devices with ability to sense environmental conditions and can change its parameters according to the requirements to get the opti...
متن کاملBiometrically Enhanced Software-defined Radios
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 and cognitive radios is our focus here. We present various means of authenticating users to their radios a...
متن کاملSynchronization in Software Radios-Carrier and Timing Recovery Using FPGAs
Software defined radios ( S D R ) are highly configurable hardware platforms that provide the technology for realizing the rapidly expanding third (and future) generation digital wireless communication infrastructure. Many sophisticated signal processing tasks are performed in a SDR, including advanced compression algorithms, power control, channel estimation, equalization, forward error contro...
