摘　　要：随着卫星通信服务宽带化、交互式的发展趋势,数字电视广播-经由卫星的交互信道标准已经广泛应用到卫星宽带互联网业务。基于卫星互联网内容监管的需要,提出了一种DVB-RCS网络IP数据非合作提取方法,并设计了一种非合作接收条件下基于信令引导的回传信道信号的检测方法,提高了回传信道信号在频域和时域的检测正确性。对实际卫星信号的测试结果表明,在非合作接收条件下,该方法能够有效提取DVB-RCS网络的IP数据。The broadband and interactive application has become the development trend of satellite communication service today.The Digital Video Broadcast-Return Channel via Satellite(DVB-RCS)standard has been widely used in satellite broadband Internet business.Based on the need of Internet content regulation,this paper proposes a non-cooperative extraction method of IP data in DVBRCS network,and designs a method to detect return channel signal based on signaling guidance under non-cooperative receiving condition,and improve the correctness of the return channel signal detection in the frequency and time domains.The test results of actual satellite signals show that this method can effectively extract the IP data of a DVB-RCS system under the condition of noncooperative receiving condition.
