FFT Implemention on FPGA for 5G Networks

University essay from Linköpings universitet/Datorteknik

Abstract: The main goal of this thesis will be the design and implementation of a 2048-point FFT on an FPGA through the use of VHDL code.The FFT will use a butterfly Radix-2 architecture with focus on the comparison of the parameters between the system with different Worlengths, Coefficient Wordlengths and Symbol Error rates as well as different modulation types, comparing 64QAM and 256QAM for the 5Gsystem.This implementation will replace an FFT function block in a Matlab based open source 5G NR simulator based on the 3GPP 15 standard and simulate spectrum, MSE payload,and SER performance.
