At Rice University, we focus on algorithms and architectures for the future generations of wireless devices that will provide hundreds of Mbits/sec processing speed, excellent quality of service, high spectral efficiency and flexibility. The Wireless Open-Access Research Platform (WARP) (http://warp.rice.edu) is being developed at the Center for Multimedia Communication (http://cmc.rice.edu). WARP provides a scalable and configurable platform mainly designed to prototype wireless communication algorithms for educational and research oriented applications. The programmability and flexibility allows for the implementation of various physical and network layer protocols and standards. Current topics of research include algorithms for multiple antenna systems (MIMO) using OFDM, along with advanced LDPC channel coding. We are also studying the extensions of these systems to cooperative or relay environments and exploring new graphic processor unit architectures and new high level synthesis design flows. Detection algorithms based on soft sphere detection (SSD) in iterative combination with outer LDPC channel decoding have great promise for improved performance. The WARP platform is reconfigurable and consists of FPGA baseband processors along with multiple attached radio subsystems, which enables quick prototyping of these wireless communication algorithms for over-the-air experimentation. The online open-access WARP repository is used to document and share different wireless architectures and cross-layer designs developed at Rice and at other educational and research centers. This repository provides a basis for students and researchers with a wide range of backgrounds in hardware implementation and algorithm development to collaborate and initiate multi-disciplinary system designs.
