为了探索超宽带(UWB)技术的空间应用,设计了一款脉冲无线超宽带(IRUWB)的全数字化相干接收机.本系统利用高速采样芯片ADC08D1000对IRUWB信号进行双通道交织采样,接下来利用Xilinx FPGA对采样数据进行降速处理.按照二分搜索、相干捕获、脉冲跟踪的方案进行接收系统设计,并对该接收机进行了实际测试.最终实现了1 ns脉宽的IRUWB信号的正确接收和1 Mb/s码速率的OOK编码通信.

@@@@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 .
