Abstract [en]

Motivated by the increase of traffic load in cellular network and the associated increase of traffic through the network, device-to-device (D2D) communication with 60GHz millimeter wave (mmWave) is a possible solution to manage this future task. In this research project, our investigation focuses on the benefits of combining D2D links and conventional links with 60 GHz mmWave.  Our investigation is performed in two phases. At first, we consider a network that has only two users, to provide a better understanding of the performance of different communication schemes with 60 GHz mmWave in simplified circumstances. Subsequently, from the realistic point of view, a multi-users system is introduced in latter to detect the relation between system throughput, antenna beamwidth, and interference model. Meanwhile, to ensure the accuracy of system performance, an accuracy improvement algorithm based on iterative algorithm is purposed in the project either.  Simulation results show that, the system with D2D communication and conventional communication together improves performance of system with pure conventional system under 60 GHz mmWave. The capacity can improve more than 13 times with 60 GHz mmWave under highly directional antenna compared with 5 GHz transmission, and system performance highly depends on antenna beamwidth and traffic load. Meanwhile, interference analysis indicates that the interference is not a significant factor for 60 GHz mmWave communication. Finally, the ratio for D2D links under different propagation conditions describes the appropriate environment of using D2D communication in network. Key words: 60 GHz millimetre wave, D2D communication, antenna beamwidth, traffic load, Interference analysis, and accuracy improvement algorithm.

Abstract [sv]

Motiverad av ökningen i mobila nätverks trafikbelastning samt även den relaterade trafiken genom nätverket. Detta projekt fokuserar på fördelarna med nätverk kombinerat D2D och konventionella länkar med 60 GHz mmWave att hantera denna framtida uppgift. Vår undersökning utförs i två faser. Först föreställer vi oss ett nätverk som endast har två användare, för att bättre förstå olika kommunikationssystem genomförs dessa i förenklade omständigheter. Därefter, från den realistiska synvinkeln, är ett multi-användar system introducerat för att undersöka förhållandet mellan systemets antennbandbrebb och störningar. Simuleringsresultat visar att kapaciteten kan förbättras mer än 13 gånger med 60GHz mmWave under en mycket riktad antenn jämfört med 5GHz överföring, och systemets prestanda är mycket beroende av antennens bandbredd och trafikbelastning. Samtidigt indikerar störningsanalys att störningen inte är en signifikant faktor för 60 GHz mmWave.
