Abstract: This paper investigates the coexistence between the fifth generation (5G) wireless sensor communication systems and Wi-Fi communication networks. The 5G wireless sensor communication system is considered as the victim system and is modelled as the Poly-Phase Network (PPN) Filter Bank Multi-Carrier (FBMC) Offset Quadrature Amplitude Modulation (OQAM) communication system, whereas the Wi-Fi communication network is considered as the interference signal. It is modelled as the Orthogonal Frequency Division Multiplexing (OFDM) based 2 × 2 Multi-Input Multi-Output (MIMO) IEEE802.11n communication signal. A closed form analytical formula to the bit error rate performance of 5G PPN FBMC OQAM communication system in presence of IEEE802.11n interference signal in additive white Gaussian noise channel is evaluated. The obtained analytical results are validated by the aid of extensive simulation results. The simulation results are experimentally done using the Software Defined Radio (SDR) Keysight SystemVue software. It will be shown that the impact of the Wi-Fi interference signal has a severe effect on the performance of the 5G PPN FBMC communication system.
