Abstract:In-Band On-Channel (IBOC) as an AM&FM digital broadcasting technology is used in HD Radio standard. In Hybrid of HD Radio, the spectra of analog FM signal and digital signal are combined in a fixed way, without taking full advantage of spectra. To solve this problem, this paper presents a Dynamic Spectrum Access (DSA) method, using the idle spectrum on time dimension. And the improved method brings in a Perceptual Evaluation of Audio Quality (PEAQ) module based on the ear perception as the evaluation crite… Show more
