Empirical Modeling of UHF Wireless Channel in HPHT SFNs: Based on Seoul Metropolitan Case

This paper proposes realistic channel models to describe the fading effects in high-power high-tower (HPHT) single-frequency network (SFN) environments. The proposed models empirically characterize the ultra-high frequency wireless channels based on field data obtained from an operational SFN in a metropolitan area. To this end, large-scale channel sounding experiments are conducted by leveraging on-air transmitter identification signals. The unique features of HPHT SFN transmission are identified and reflected in the tapped delay line parameter definitions. Dedicated models are built for stationary and mobile environments so that they could relevantly assist network planning, system implementation, and performance test in the industry. Free MATLAB source code of the fading simulator is available at https://github.com/ETRI-KMOU/FadingChannelSimulator.
