Abstract

This reseach simulates and analyzes paramaters bit error rate (BER) of 16-QAM and 64-QAM modulation on Additive White Gaussian Noise and Rayleigh Fading channels. This research aims to determine 5G modulation with the level of data quality after the transmission process is carried out. The modulation simulation results obtained will be compared with the theoretical bit error rate (BER). The simulation results obtained from the two channel scenarios used are 16-QAM modulation reaching BER 10-4, AWGN channel only requires 15 dB Eb/N0 and for Rayleigh Fading channel it requires 38 dB Eb/N0. The BER theoretical results obtained for the 16-QAM modulation of the AWGN channel have a difference of 3 dB with the simulation results, while for the Rayleigh Fading channel it is 5 dB. Then, the simulation results of 64-QAM modulation AWGN channel to achieve BER 10-4 requires Eb/N0 of 24.6 dB, Rayleigh Fading of 47 dB. The theoretical results of BER obtained for the 64-QAM modulation of the AWGN channel have a difference of 1 dB with the simulation results, while for the Rayleigh Fading channel it is 0.5 dB. In this study, between 16-QAM and 64-QAM 5G modulation is more suitable to use 16-QAM modulation because it requires less power to achieve the desired BER 10-4.

Abstract

Penelitian ini melakukan optimasi pada jaringan microwave site Cipetir-Cibadak dengan menggunakan space diversity dengan frekuensi kerja 32 GHz. Kondisi wilayah site Cipetir-Cibadak merupakan daerah perbukitan dengan jarak 11,42 Km, sehingga diperlukan penambahan antena diversity. Optimasi jaringan microwave ini dilakukan menggunakan software Pathloss 5.0 untuk melihat perbandingan sebelum dan sesudah menggunakan antena diversity. Parameter yang digunakan pada performansi optimasi jaringan microwave ini adalah availibility yang diperoleh berdasarkan simulasi menggunakan vigent barnet dan ITU-R. Nilai availibility yang diperoleh sebelum optimasi berdasarkan vigent barnet 99,86112% dan ITU 99,87924%, setelah pemasangan antena diversity pada jarak 100l, 125l, 150l, 175l dan 200l dan pada jarak 200l nilai availibility meningkat berdasarkan vigent barnet 99,91027% dan ITU-R 99,9118%. Penggunaan teknik space diversity ini dapat meningkatkan kehandalan sistem.
