Observations of radio wave pulses from super massive black holes located in the center region of our Galaxy have been made by cosmic radio observation system at the Awara campus of Fukui University of Technology in the frequency range of the decimeter (1.4GHz bands) and centimeter waves at 8.4GHz (X band). Analyses of the data utilizing the FFT and box-car methods show that there are pulse components of radio waves in the observed data in the decimeter and the centimeter wavelength range. The detected pulse periods in the decimeter radio wavelength range show both the same and different components of the periods from the case of the pulse periods of decameter radio pulses from the center region of our Galaxy which have been identified to be radiated from the rotating super massive black holes ; the pulses in the centimeter wavelength range indicate different periods with the case of decameter radio waves. It has been clarified that the features of frequency dependence of pulse periods reflect the positions of sources of corresponding frequency range that are located in the region close to the event horizon of Kerr black holes.
