Title: (EN) TIME DOMAIN INGRESS NOISE DETECTION AND CANCELLATION
(ZH) 时域入口噪声检测和消除
Abstract: front page image
(EN) An apparatus, comprising a receiver configured to receive a primary signal that comprises a narrowband noise component and a broadband noise component, a processor coupled to the receiver and configured to determine, in a time domain, an estimate of the narrowband noise component in real-time, determine a cancelled output signal in real-time that comprises an estimate of the broadband noise component, and determine an estimate of a power level of the narrowband noise component in real-time.
(ZH) 一种装置,包括:接收器,用于接收包括窄带噪声分量和宽带噪声分量的主信号;处理器,与所述接收器耦合,并用于在时域中实时确定所述窄带噪声分量的估值,实时确定包括所述宽带噪声分量的估值的消除的输出信号,并实时确定所述窄带噪声分量的功率电平的估值。
