This paper studies the spectrum occupancy in the frequency between 87.5 MHz and 108 MHz allocated for radio broadcasting in China. Through analyzing spectral measurement results, we can be identified the “spectrum holes”, which provide the possible candidates for CR operations, a promising solution to alleviating the heavy pressure on the scarce radio spectrum. Furthermore, it also plays the guiding role when detecting the illegal radio broadcasting, attributing to maintaining the radio order. More specifically, we can be found the actual spectral usage in this band, which provide statistics for white spaces of the whole spectrum and obtain spectrum occupation time and ratio.
