Abstract:Abstract-We present a digital hardware model for ultra wideband channels. The system runs at 80 MHz on a Xilinx Virtex-4 xc4vsx35 FPGA. High-speed arithmetic operations including division, square root, powering and normal random number generator are analyzed and developed for use as basic components in the channel emulator. The design flow is based on Matlab Simulink as the model builder, followed by Xilinx System Generator to transform the Simulink model into a VHDL description which can be synthesized and ma… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
