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.

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

Based on new signal generation technologies such as vector signal modulation and arbitrary waveform editing and playback, the transmitter resources are multiplexed by each signal component at the same time or sharing time to generate flexible and dense composite signals and solve the problem of complex electromagnetic environment construction under the limited hardware.
