Abstract :
In recent years, electronics and large appliances became popular. However, a noise from the appliances would interfere with radio communication system. The artificially generated noise from the appliances has a periodicity in frequency. In this paper, a periodical noise suppression system using a frequency shift is proposed. Suppression effect for the periodical noise by the proposed system is confirmed when periodical noise is large. Furthermore, effect of frequency shift error on the suppression effect is described.
