Investigation on effectiveness of Interference mitigation and scheduling Policies between new radio nr and Device to device systems in 5g

Abstract

The telecommunication industries manifest a periodic modification to address the necessities of the public around the world. Also, commercial corporations fabricate and launch radio access devices with astonish features every day. All these facilities attract users with large quantities towards it and indulge in high demand for rapid network access and mass device connectivity with high throughput. The existing fourth generation technology is no longer supportive to meet such desire. Thus transformation towards the new generation becomes an essential part of the industrial revolution. The upcoming fifth generation (5G) is expected to expose a new venture in the communication industry. Device to device Communication (D2D) and Internet of Things (IoT) are the two key technologies of 5G systems. The proposed system abides to follow the protocols specified by the Third Generation Partnership Project (3GPP), Federal Communication Commission (FCC) and International Telecommunication Union (ITU) for D2D communication underlying cellular network. The thesis encourages the physical and link layer design of 5G cellular systems. For this purpose, multi carrier modulation schemes such as Orthogonal Frequency Division Multiplexing (OFDM) and Generalized Frequency Division Multiplexing (GFDM) are designed with linear iterative receivers such as Matched Filter (MF), Zero Forcing algorithm (ZF) and Minimum Mean Square Error Equalizer (MMSE). Further, Frequency domain Equalization (FDE) and diversity combing schemes such as Equal Gain Combining (EGC) and / or Maximal Ratio Combining (MRC) are jointly introduced to provide compensation for channel fading effects. newlineThe next consideration here is the hybrid 5G system, which has the potential to operate in different frequency bands. newline
