9818315Liu, HuiAzizoglu, MuratUniversity of WashingtonCISE Research Instrumentation: A Broadband Software Radio Testbed for Research in Wireless CommunicationsThis research instrumentation enables research projects in:- Wireless Laboratory Enhancement,- DSP Solutions for Low Complexity Multi-User Detectors, and- Bit-Interleaved Coded Modulation for Wireless Data Network.To support the aforementioned projects, the Department of ElectricalEngineering at the University of Washington will purchase microware testingequipment and computing facilities for upgrading an existing wirelesscommunication laboratory. The equipment is used to set up a broadbandsoftware radio testbed which consists of a multichannel RF transceivermodule, a multiple broadband data acquisition system (10Ms/c/s), anarbitrary RF signal generator, and a wireless channel fading simulator. Thenew testbed enables experimental research in the areas of broadbandmultiple-access, multiuser detection, time/space diversity combining,wireless networking, as well as other potential multidisciplinary researchrelated to personal communication services (PCS). Both the quality andscope of on-going and future research in wireless technology is enhancedby the proposed instrumentation. Anticipated impacts of this projectinclude larger capacity, better interference and fading resistance, andhigher power efficiency and system flexibility for wireless systems.
