| 摘 要： | 为提高地面数字电视广播(DVB-T)接收机的实现灵活性,基于由通用软件无线电外设(Universal Software Radio Peripheral,USRP)和通用计算机组成的软件无线电平台,实现DVB-T接收机。接收机以USRP作为射频前端,在通用计算机中完成全部基带信号处理、视频解码与显示等。测试结果表明,接收机可实现对DVB-T信号的接收,为接收机算法开发、验证与评估提供了更为灵活的方法。

| Abstract: | To improve the implementation flexibility of Digital Video Broadcasting-Terrestrial (DVB-T) receiver, a DVB-T receiver is implemented based on a software-defined radio platform composed of the Universal Software Radio Peripheral (USRP) and a general purpose computer. At the receiver, the USRP acts as a radio frequency front-end. Signal processing, video decoding and displaying are all implemented on the general purpose computer. Test results show that, the receiver can realize the reception of DVB-T signal and provide a more flexible method for algorithm design, verification and evaluation. |
