Interference Coexistence Analysis Between IMT-2020 System and Radar in the Same Frequency Band

Abstract

Due to the interference coexistence between IMT-2020 system and radio locating radar system in the 3 400 ∼3 600 MHz frequency band, based on the coexistence scenario of this frequency band, this paper sorts out the typical frequency parameters of radar and the key parameters of base station, and establishes a propagation model. The interference between IMT-2020 system and radar system in the same frequency band is analyzed by means of system modeling and Monte Carlo simulation. According to the interference threshold of the system, the interval distance required for the coexistence of the two systems is obtained, and the interference avoidance measures are proposed to realize the coexistence of the two systems.
