Abstract
Dengan perkembangan 5G, terdapat beberapa kandidat waveform baru, salah satunya adalah Filter Bank Multi Carrier (FBMC). Karena FBMC lebih baik dibandingkan Orthogonal Frequency Division Multiplexing (OFDM) dalam hal efisiensi spektral dan ketahanan terhadap Inter Symbol Interference (ISI) dan Inter Carrier Interference (ICI), FBMC diharapkan dapat menjadi sistem yang bekerja lebih baik diberbagai bidang teknologi, seperti komunikasi Vehicle to Vehicle (V2V) pada teknologi Vehicular Ad Hoc Network (VANET). Kinerja komunikasi V2V dipengaruhi oleh frekuensi Doppler yang muncul dari perubahan kecepatan kendaraan and scatter disekitar yang mengakibatkan degradasi kinerja. Selain itu, adanya intrinsic interference pada FBMC menyebabkan degradasi kinerja karena FBMC tidak dapat menghadapi frekuensi Doppler yang muncul di kanal V2V.
Penelitian ini menganalisa kinerja sistem FBMC/OQAM yang bekerja pada kanal V2V dan menyebabkan adanya efek Doppler. Hasil dari simulasi menunjukkan bahwa nilai rata-rata Bit Error Rate (BER) sistem FBMC/OQAM adalah 0.4 dan 0.45 masing-masing untuk sistem 4-ary dan 16-ary saat melewati kanal V2V. Selain itu kinerjanya mengalami ketidakstabilan dengan nilai variansi BER untuk sistem 4-ary dan 16-ary masing-masing adalah 0.01 dan 0.003. Untuk memperbaiki kinerja sistem FBMC/OQAM, dilakukan simulasi sistem dengan variasi rentang nilai sudut dari Angle of Departure (AoD) dan Angle of Arrival (AoA) dari setiap path yang digunakan pada kanal komunikasi V2V. Hasil dari simulasi menunjukkan bahwa sistem FBMC/OQAM akan memiliki rata-rata BER 0.0018 dan 0.0035 bila nilai rentang sudut AoD dan AoA yang digunakan adalah (−0.1
================================================================================================
Along with the development of 5G, there are several new waveform
candidates, one of them is Filter Bank Multi-Carrie (FBMC). Because FBMC is
superior to Orthogonal Frequency Division Multiplexing (OFDM) in the field of
spectral efficiency and robustness against Inter Symbol Interference (ISI) and Inter-
Carrier Interference (ICI), FBMC is expected to be a system that can work better
in various fields of technology, such as in Vehicle-to-Vehicle (V2V) communication
on Vehicular Ad-hoc Network (VANET) technology. The performance of V2V
communication is influenced by Doppler frequency which arises from the change
of vehicle speed and the scatter around that makes performance degradation.
Additionally, the presence of intrinsic interference in FBMC leads to performance
degradation because it cannot withstand the Doppler frequency that is existence in
the V2V channel.
This paper will analyze the performance of the FBMC/OQAM system that
works on the V2V channel and lead to the presence of Doppler Effect. The result
from the simulation shows that the Bit Error Rate (BER) mean of FBMC/OQAM
system are 0.4 and 0.44 respectively for system 4-ary and 16-ary through V2V
channel. Other than that, the performance also suffers from the instability by BER
variance for system 4-ary and 16-ary are 0.15 and 0.19. To improve FBMC/OQAM
performance, simulation with the variation of the range value of Angle of Departure
(AoD) and Angle of Arrival (AoA) of each path that is used in V2V channel
simulation is done. The result shows that the FBMC/OQAM system will have BER
mean 0.0018 and 0.0035 if the range value of AoD and AoA that is used are
(−0.1, 0.1) fro 4-ary and (−0.075, 0.075) for 16-ary. Even though
FBMC/OQAM performance’s increase, it still cannot surpass OFDM
performance’s that work on V2V channel with the same range angle value for AoD
