Title: Physical Layer Waveform Approaches for Fifth Generation Cellular Network
Author: Hassan, Alzahra Abdul Rahman Ali
Abstract: International Mobile Telecommunications 2020 (IMT-2020), also known as the Fifth Generation (5G), is the next technological revolution in mobile broadband. One of the very important research areas is the physical layer architecture and waveform techniques of the 5G network. To maximize spectrum efficiency, the 5G air interface technology will also need to be flexible and capable of mapping various services to the best suitable combinations of frequency and radio resources. So this thesis describes 5G mobile networks concepts, principles and processes. and investigates the physical layer waveform approaches as part of enhanced mobile broadband use case in 5G, and finds Cyclic Prefix - Orthogonal Frequency-Division Multiplexing (CPOFDM) a suitable approach by comparing performance parameters where the filtering and windowing can result in degradation of the quality of the signal which is measured via Error Vector Magnitude (EVM). It also tries to enhance the down link performance between the base station and user equipment by using power amplifier clipping technique and describes the downlink channel modeling by implementing channel coding, synchronization signal burst generation, different subcarrier spacings and frame numerologies in different propagation channel and with different waveform approaches. The last step in investigating the physical layer aspects is to demonstrate the transmission using the recent simulation programs MATLAB, SYSTEMVUE and Vector Signal Analyzer (VSA) and measure parameter metrics.
