Study on the interference of harmonics and intermodulation in proximity service links for 5G mobile system

In this paper, an interference model for multi-hop links has been studied and analyzed. To address the performance of interference model, both harmonic and intermodulation interferences under different frequency bands are studied and calculated for the heterogeneous networks of 5G and Wi-Fi scenarios. The simulation results for system performances in multi-hop links are conducted and analyzed in conjunction with an interference station with power of 29 dBm and working frequency of 2132.5 MHz. The results of throughput and delay in the mobile system are consistent with the theorical expectations. And the interfering nodes had a relatively small impact on the overall throughput in the cell, which means that this multi-hop 5G system possess a robustness for interference.
