Abstract:

Government agencies have a long history of dedication to the use of severe surveillance measures on potentially hazardous persons or their communications as part of their responsibility to safeguard the nation. This work looks at a wireless legitimate surveillance system in which a fullduplex multi-antenna legitimate monitor forcefully interrupts the communication channel of a suspicious couple to eavesdrop on them. While solutions like massive MIMO, tiny cells, and full duplex will help eliminate interference in future 5G communication systems, it remains one of the most formidable obstacles to be overcome. So, this work outlines a strategy for dealing with interference in a Heterogenies network (HetNet) that combines an multi base station (MBS) with multiple input multiple output (MIMO) technology with many surveillances base stations (SBS) capable of full duplex communication. In each case, we calculate the ideal jamming strength using closed-form calculations and provide efficient methods for finding the best transmit and receive beamforming vectors.Suboptimal beamforming techniques with minimal complexity have extra support in the MIMOscenario. This research indicates that directing MBS towards the authorized monitor may greatly improve the odds that eavesdropping won't lead to a disruption. The Eavesdropping non-outage probability (ENOP) performance of proposed methodimproved over other methods.

Keywords: Multiple input multiple output, Heterogenies network, surveillances base stations, multi base station, biterror rate.
