ABSTRAK

Jaringan 5G telah menjadi penanda penting dalam evolusi teknologi nirkabel yang menawarkan kecepatan dan kinerja yang luar biasa untuk memenuhi kebutuhan konektivitas yang semakin meningkat. Dalam jaringan 5G, pengkodean kanal merupakan elemen penting dalam memastikan pengiriman data yang handal dan efisien. Penelitian ini mengkaji sistem 5G pada frekuensi 26 GHz dan bandwidth  200 MHz menggunakan Orthogonal Frequency Division Multiplexing (OFDM) dengan ukuran Fast Fourier Transform (FFT) sebesar 256 dan modulasi Binary Phase Shift Keying (BPSK). Penelitian ini mengevaluasi perbandingan penambahan channel coding yaitu QC-LDPC dan polar codes. Performansi QC-LDPC codes pada BER sebesar 10-4 dapat dicapai dengan SNR 𛾠= 17 ð‘‘ðµ untuk kode QC-LDPC dan SNR 𛾠= 15 ð‘‘ðµ untuk polar codes. Hasil menunjukkan bahwa penambahan channel coding mampu menangkap diversity order kedua dan performansi polar codes lebih baik dibandingkan dengan QC-LDPC.

ABSTRACT

The 5G network has become a significant milestone in the evolution of wireless technology, offering remarkable speed and performance to meet the growing demands of connectivity. In the 5G network, channel coding is a crucial element to ensure reliable and efficient data transmission. This research evaluate the 5G network operating at a frequency of 26 GHz and a bandwidth of 200 MHz, utilizing Orthogonal Frequency Division Multiplexing (OFDM) with an Fast Fourier Transform (FFT) size of 256 and Binary Phase Shift Keying (BPSK) modulation. The research evaluates the comparison of adding channel coding using QC-LDPC and polar codes. The performance of QC-LDPC codes at a bit error rate (BER) of 10-4 can be achieved with an SNR of 𛾠= 17 ð‘‘ðµ for QC-LDPC codes and an SNR of 𛾠= 15 ð‘‘ðµ for polar codes. The results shows the addition of channel coding is capable of capturing second-order diversity, and polar codes outperforms QC-LDPC in terms of performances.
