    Wireless communication standards are developed at an ever-increasing rate of pace, and significant amounts of effort is put into research for new communication methods and concepts. On the physical layer, such topics include MIMO, cooperative communication, and error control coding, whereas research on the medium access layer includes link control, network topology, and cognitive radio. At the same time, implementations are moving from traditional fixed hardware architectures towards software, allowing more efficient development. Today, field-programmable gate arrays (FPGAs) and regular desktop computers are fast enough to handle complete baseband processing chains, and there are several platforms, both open-source and commercial, providing such solutions. The aims of this paper is to give an overview of five of the available platforms and their characteristics, and compare the features and performance measures of the different systems.

    WARP, a Modular Testbed for Configurable Wireless Network Research at Rice
    (IEEE, 2007-03-01) Amiri, Kiarash; Sun, Yang; Murphy, Patrick; Hunter, Chris; Cavallaro, Joseph R.; Sabharwal, Ashutosh; Center for Multimedia Communication
    Wireless Open-Access Research Platform (WARP), developed at CMC lab, Rice University, provides a scalable and configurable platform for wireless network research. Its programmability and flexibility makes it easy to prototype and implement various physical and network layer protocols and standards. In order to share algorithms and implementations developed at different research centers, an online open-access repository is used so that wireless network researchers can collaborate to initiate multi-disciplinary system designs.

    WARP, a UnifiedWireless Network Testbed for Education and Research
    (IEEE, 2007-06-01) Amiri, Kiarash; Sun, Yang; Murphy, Patrick; Hunter, Chris; Cavallaro, Joseph R.; Sabharwal, Ashutosh; Center for Multimedia Communication
    In this paper, we introduce the Wireless Open-Access Research Platform (WARP) developed at CMC lab, Rice University. WARP provides a scalable and configurable platform mainly designed to prototype wireless communication algorithms for educational and research oriented applications. Its programmability and flexibility makes it easy to implement various physical and network layer protocols and standards. Moreover, the online open-access WARP repository is used to document and share different wireless architectures and cross-layer designs developed at educational and research centers. This repository is a fast and easy solution for students and researchers with a wide range of backgrounds in hardware implementation and algorithm development to collaborate and initiate multi-disciplinary system designs.
