Performance Evaluation of HD Radio System in Radio Environments

The advance of wireless communications brings in various schemes of wireless digital communication technology. Analog communication and broadcasting services convert into digital services in many countries. The IBOC (In- Band On-Channel) system has been developed to work in the same band with the conventional analog radio and broadcasting digital signal simultaneously. HDR (HD-Radio) standard of IBOC can use coherent demodulation using pilot subcarriers. In this paper, the performance of HD radio system is evaluated. To contribute to decision of digital radio standard and design of digital radio transmission network, the simulation results will give a help.
