流氓无线电造成的有害干扰对频谱共享生态系统构成严重威胁。在这种方法中验证其波形，正在验证波形的执行实体不是预期的接收器在现实情况下，几乎不了解传输参数的“盲目”来解码身份验证信号，执法实体可能需要应对其他挑战，包括收到的信号的信号强度差发射器。共沟通发射器（CBAT）。我们还提出了该概念的具体实例众包的力量。
The harmful interference caused by rogue radios poses a serious threat to spectrum sharing ecosystems. One approach for mitigating this problem is to adopt an enforcement scheme that can be used by an enforcement entity (e.g., Federal Communications Commission’s Enforcement Bureau) to uniquely identify transmitters by authenticating their waveforms. In this approach, the enforcement entity that is authenticating the waveform is not the intended receiver, and hence it has to decode the authentication signal “blindly” with little or no knowledge of the transmission parameters. In real-world scenarios, an enforcement entity may need to cope with additional challenges, including poor signal strength of the received signals and simultaneous co-channel transmissions from multiple transmitters. In this paper, we propose a novel concept that effectively addresses some of these challenges, which we refer to as crowd-sourced blind authentication of co-channel transmitters (CBAT). We also present a concrete instantiation of this concept called frequency offset embedding for CBAT (FREE). Our results show that FREE enables the enforcement entity to blindly authenticate multiple co-channel transmitters with good accuracy by harnessing the power of crowd-sourcing.
