| Abstract(in English) | In FM-radio on motor vehicles, there exists an interference called as a beat noise which is an electromagnetic radiation caused from electronic devices equipped on motor vehicles. The beat noise provides a noise sound and breaks a part of a desired speech signal. Since the noise and the speech degradation are perceptually annoying, the beat noise should be suppressed. It is required that the noise suppression is achieved by using a low cost device that is a DSP of a low clock frequency. The proposed method is a sinusoidal suppressor which consists of two adaptive line enhancers. The proposed method is applied to a modified signal in the demodulation process. Simulation results show the effectiveness of the proposed method. |
