Design of an IR-UWB Coherent Receiver Based on High-Speed ADC and FPGA

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-interleaved-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.
