A Dynamic Spectrum Access Method for IBOC Broadcasting Based on the Ear Perception

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 criterion to measure audio quality. The simulation results show that on the basis of insuring audio quality, this method can save a lot of spectral bandwidth to improve the available spectrum resources.
