Influence of interferences caused by non-linear power amplifier in multi-user Generalized Frequency Division Multiplex scenario

Popis výsledku v původním jazyce

This article is aimed to the problematic of interferences in multi-user scenarios which can occur in modern mobile communication networks. Hence of new modulation schemes as a Filter Bank Multi Carrier (FBMC), Generalized Frequency Division Multiplex (GFDM) or another modulation scheme with low out of band emission there can occur problems with interferences especially when user equipments are using non-linear power amplifiers. The non-linear system causes radiation into adjacent channel which can lead to interferences with another user transmitting in this channel. This paper explains impact of such interferences to Error Vector Magnitude (EVM) of demodulated signal for different frequency spacing between users and also describe influence of interferences for different signal noise ratio. To remove inter-carrier interferences, the self interference cancellation method is used.} keywords{Power amplifier, amplifier modeling, distortion, interferences, FBMC, GFDM, 5G
