Friday on 21 June 2019, a researcher of Center for Advanced Wireless Technology (AdWiTech) has succeed his Final Defense in P203 Room (AdWiTech Laboratory) with Bachelor Thesis title “Study on OFDM Numerology 5G New Radio (NR) Performances Under Indonesia 5G Channel Model”.
Kumara Panji Atmaja, as a part of 5G-POINT member, did research studies about 5G NR technology performances using Orthogonal Frequency Division Multiplexing (OFDM) with Numerologies 0, 1, 2, 3, and 4 under Indonesia 5G channels to serve various future 5G technology needs. This research calculates and evaluates the outage performances of Indonesia 5G channels, which are also validated using bit error rate (BER) and frame error rate (FER) performances simulation. The simulation is based on OFDM Numerology concept in 5G NR standards with several cyclic prefix (CP) sizes and modulations according to the 5G services.
This research is also in part supported the INSINAS Ristek Dikti Funding under the 5G-POINT (Preparing Optimal 5G Indonesia Networks) project during 2018-2019. The results of this research are evaluation result of 5G NR performances in Indonesia for various Numerologies and evaluation result of potential parameters to be optimized to achieve 5G maximum performance in Indonesia. This research shows the characteristics of OFDM Numerologies 0, 1, 2, 3, and 4 under Indonesia 5G channels i.e., achieved diversity order of outage performances, energy per bit-to-noise power spectral density ratio () value at BER performances of 10-4, number of paths obtained for each Numerology with the power of each path, and gap between obtained BER performances and existing theory. This research also provides table of power analysis based on different modulations for OFDM Numerologies 0, 1, 2, 3, and 4 which is expected to be an accurate reference for hardware development in Indonesia.
