Tiivistelmä
Society is in a process of continuous innovation, where the requirements are more and more demanding. Therefore, new mobile network technologies appear with the objective of meeting all these new needs, such as 5G New Radio.

The goal of this thesis is to analyze 5G New Radio in high speed scenarios, implementing it in MATLAB according to 3GPP specifications. Starting with MATLAB’s 5G Toolbox, certain modifications are made in order to test all the different scenarios for some chosen velocities. To do this, different values of a series of parameters that affect the throughput are tested. Hence, the throughput is the characteristic used to measure the performance of 5G New Radio in this thesis.

Among these parameters are the subcarrier spacing, the carrier frequency and the number of DMRS reference symbols. Once this is known, different configurations are made, analyzing how they affect the throughput, focusing mostly on two high velocities: 160 km/h and 240 km/h. The results show that increasing the spacing subcarrier and the number of DMRS symbols, increases the throughput also, while it is decreased if either the carrier frequency or the user’s speed increases, as the last ones increase the Doppler shift.

Finally, a comparison is made between the waveform proposed by 5G New Radio, CP-OFDM, and an alternative called UW-OFDM. This UW-OFDM brings numerous benefits compared to CPOFDM, and it is concluded that the throughput it offers is superior to the one CP-OFDM offers in these high speed scenarios.
