| Abstract(in English) | In this paper a noise suppression system using quadrature demodulation techniques and fast fourier transformation(FFT) is considered to reduce the effect of the interfering. The suppression system utilizes a fact that the quadrature signal includes only the interference, while the in-phase signal from the demodulator includes both of AM signal and interference. To cancel the noise component in the in-phase signal, the noise component in the quadrature signal is adjusted by a replica signal because the sign of the both interference is different each other. FFT is used by the system because the replica signal is generated by a complex correlation value on frequency domain. Thus, the interference in the in-phase signal can be canceled by the quadrature signal. |
