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

Sistem jaringan selular indoor merupakan salah satu solusi untuk mengatasi lemahnya sinyal yang dipancarkan oleh eNodeB. Gedung dengan tingkat trafik komunikasi selular yang padat, seperti gedung konferensi, sekolah/kampus, perkantoran, pusat swalayan dan bandara memerlukan sistem jaringan indoor untuk menjaga kelangsungan komunikasi selular dan kebutuhan bit rate yang tinggi oleh semua user. Oleh karena itu, perlu dilakukan perencanaan jaringan indoor dengan menggunakan femtocell LTE. Penulisan Penelitian ini merancang jaringan indoor LTE di gedung kampus ST3 Telkom Purwokerto lantai 1 dan 2 berdasarkan model propagasi COST 231-Multiwall Indoor dengan menggunakan aplikasi Radiowave Propagation Simulator (RPS). Parameter yang dibutuhkan untuk perancangan jaringan selular indoor yaitu luas gedung, jenis material gedung dan jumlah user untuk mengetahui jumlah Femtocell Access Point (FAP) yang dibutuhkan agar semua ruangan dapat tercover dan mendapatkan sinyal yang bagus. Dari hasil perhitungan coverage, dengan total luas area yang direncanakan 1482 m2 dibutuhkan 10 FAP. Perancangan menggunakan 3 skenario, skenario terbaik adalah skenario 2 (FAP diletakkan di tengah-tengah setiap ruangan) menghasilkan level daya sinyal yaitu -63.91 dBm dan Signal to Interference Ratio (SIR) sebesar 3.00 dB. Untuk alokasi Physicall Cell Identity (PCI) total ada 10 nomor sesuai dengan jumlah FAP, karena tidak ada pembagian sektor pada setiap Femtocell Access Point (FAP).

Abstract

This research using a polar code and without polar codes -based broadband channel that is affected by human blockage using one of the 5G cellular network frequencies at 2.3 GHz, 99 MHz bandwidth, 128 blocks of Fast Fourier Transform (FFT) with Cyclic prefix-Orthogonal Frequency Division Multiplexing ( CP-OFDM) and Binary Shift Keying (BPSK) modulation. The use of high frequencies causes the technology to be sensitive to the surrounding environment and attenuation such as human blockage. The purpose of this research is to determine the performance results and analyze the BER parameters that use polar codes and without polar codes on 5G network broadband channels that are affected by human blockage. Broadband channel modeling on a 5G network is presented in a representative Power Delay Profile (PDP) with the influence of human blockage, which is obtained as many as 41 paths which have multiple delays of 10 ns on each path. This research also uses the scaling method on representative PDP because the use of FFT will produce 128 blocks, and the results of this scaling show that there are 9 lanes with multiple delays of 50 ns. The results of this study are close to the average Bit Error Rate (BER) of 10-4. BER performance without polar code is affected by human blockage requires Signal to Noise (SNR) of 30 dB, for theory BER on BPSK modulation requires SNR of 34.5 dB and BER performance using polar code only requires SNR of 23 dB. These results indicate that using a polar code can reduce or save power usage by 7 dB without a polar codes. Polar codes can minimize errors in the 5G network system, because polar codes are one of the strong codes and are one of the channel coding recommended by ITU to be applied to 5G network systems

Abstract

This research designed a 5G NR network using 700 MHz and 2.3 GHz frequencies with 30 MHz bandwidth in the Jababeka industrial area covering an area of 5600 hectares. The Propagation Model used by Urban Macrocell (UMa) in non line of sight (NLOS) conditions according to 3GPP TR 38901 standard with Synchronization signal-reference signal received power (SS-RSRP) and Synchronization Signal to Interference and Noise Ratio (SS-SINR) parameters. Coverage prediction simulation using Atoll 3.4 consists of 4 scenarios. Scenario 1 uses a frequency of 2.3 GHz downlink, scenario 2 uses a frequency of 2.3 GHz uplink, scenario 3 uses a frequency of 700 MHz downlink and scenario 4 uses a frequency of 700 MHz uplink. Parameters analyzed were signal strength (SS-RSRP > -110 dBm) and signal quality (SS-SINR > 5 dB). The simulation results of scenario 1 get a signal strength of 61% and signal quality of 73.71% from the Jababeka area. Scenario 2 gets 100% for signal strength and 75.35% for signal quality. Scenario 3 gets a signal strength of 72.27% and signal quality of 85.30%. Scenario 4 shows a signal strength of 100% and signal quality of 71.04% from the Jababeka area. Planning with a frequency of 700 MHz shows that the signal strength and signal strength parameters are better than the 2.3 GHz frequency, making it suitable for 5G networks in the Jababeka area. The findings of this study are intended to help Indonesian cellular operators plan and deploy their 5G network.
