下一代无线实验受益于新的大规模开放接入软件定义无线电（SDR）平台。每个SDR的传输必须被测量和监控，以保证频谱合规性。然而，所测量的频谱被外部同信道信号破坏。本演示介绍了双向入射/发射信号分离器（BITSS），该系统可在没有信号先验或系统信息的情况下，实时估计线性系统模型、SDR的发射信号以及入射到天线的其他源信号。我们在POWDER上实现并运行了BITSS，并对其性能进行了评估。演示表明，BITSS能够在一系列信号参数上实现高精度分离，并在发生频谱违规时提醒用户和运营商。
Next-generation wireless experimentation benefits from new large-scale open-access software defined radio (SDR) platforms. Each SDR's transmissions must be measured and monitored to guarantee spectrum compliance. The measured spectrum is, however, corrupted by external co-channel signals. This demo presents the Bidirectional Incident/Transmit Signal Separator (BITSS), a system which estimates the linear system model, the SDR's transmit signal, and the signals from other sources incident to the antenna, all on the fly and without a signal prior or system information. We implement and run BITSS on POWDER and evaluate its performance. The demo shows that BITSS enables separation over a range of signal parameters with high accuracy and alerts users and the operator whenever a spectrum violation occurs.
