Performance of interference suppression system in environment where artificial noise is mixed into multiple desired signals

摘要

Recently, electromagnetic interference in AM radio receivers associated with noise generated from the power control unit (DC-DC converters) in hybrid vehicles (HVs) has becomes a serious problem. To address this problem, a noise suppression method thorough digital signal processing in an AM radio is proposed in the past research. However, the method is only applicable to single desired signal. In this paper, the reduction performance by the method for multiple desired signals is confirmed.
