摘要

Abstract

In order to investigate the application of ultra wideband (UWB) for satellite communication, a digital coherent receiver is designed for impulse radio ultra wideband ( IRUWB) . In the system, dualchannelinterleavedsampling is used to digitize the analog IRUWB by a highspeed ADC (ADC08D1000), and the sampled data is decelerated by Xilinx FPGA . IRUWB signal is received through binarysearching, coherent capturing and pulse tracking . The receiver is tested and the result shows it can receive 1ns UWB pulse accurately and communicate at 1Mb/s .
