Abstract

Single Carrier Frequency Division Multiple Access (SCFDMA) merupakan teknik multiple access menggunakan single carrier dalam mengirimkan data yang diimplementasikan pada sisi uplink 4G. Inter symbol interference (ISI) yaitu suatu gangguan yang besar untuk efisiensi transmisi pada data digital, ISI terjadi saat deretan data simbol yang saling tumpang tindih (over lapping), sehingga diperlukan suatu teknik ekualisasi yaitu Decision Feedback Equalizer (DFE) sebagai metode mengatasi ISI. Tujuan penelitian ini dilakukan analisis kinerja DFE pada sistem komunikasi SCFDMA melalui kanal AWGN dan Rayleigh Fading dengan parameter Symbol Error Rate (SER). Penelitian ini menghasilkan unjuk kerja DFE pada sistem komunikasi SCFDMA melewati kanal AWGN dan Rayleigh Fading. Pada kanal AWGN  yaitu saat sistem menggunakan DFE nilai pada SER mencapai 10-3  menghasilkan Es/No 8 dB, sedangkan tanpa DFE nilai SER mencapai 10-3 menghasilkan Es/No yang besar 14 dB. Pada kanal Rayleigh Fading saat menggunakan DFE nilai SER mencapai 10-3 menghasilkan Es/No 8 dB, sedangkan tanpa DFE hanya mencapai dimana nilai SER mencapai 10-2 menghasilkan Es/No yang besar yaitu 30 dB. Jadi unjuk kerja sistem SCFDMA yang lebih baik pada saat menggunakan DFE yaitu menghasilkan nilai SER mencapai 10-3 sesuai dengan standar komunikasi.

Abstract

The Internet has become a basic need for every human being in carrying out his activities. To find out the quality of the internet network, a measurement called the Quality of Service is needed. Quality of service measurement can help in evaluating the performance of internet network providers. Data collection was carried out by monitoring while using YouTube and conducting video meetings using the Zoom application using the Wirleshark software with a viewing time of 30 minutes using the 10 Mbps Iconnet package. The number of users of the Iconnet internet network in this study amounted to 5 users. The data collected in this study were processed using QUALITY OF SERVICE parameters such as throughput, packet loss, delay, and jittler. Then an analysis was carried out by comparing the data obtained with the TIPHON standard. Data collection was carried out at Bumi Mi'Raj Housing, Jalan Bangau Sakti, Pekanbaru City. The results of the 10 Mbps iconnet network research have a very good delay value with an average of 21.75 ms and a very good packet loss with an average of 0.46%. The jitter parameter is in the good category with an average of 24.80 ms and the throughput parameter is in the bad category with an average of 258 kbps. The use of the 10 Mbps iconnet network can be used to play Youtube videos with 360p quality resolution with a total of 5 users. The more users of the 10 Mbps iconnet network, the effect will be a decrease in the quality of the Quality of Service parameter. The use of the iconnet network is better used on the slowest walk than on the slowest time.

Abstract

The FSO communication system is a communication system that uses the atmosphere as a propagation medium for light, which is used as an optical source to transmit data to the receiver. Due to using the atmosphere as a propagation medium causes the FSO communication system to be susceptible to signal weakening caused by varying atmospheric attenuation. So, it is necessary to conduct research on FSO performance based on atmospheric conditions. This research carried out communication design using FSO technology in Pekanbaru City, analyzing the influence of rainy weather and wind data using FSO MIMO. After analyzing and optimizing the parameters contained in the FSO device to achieve the best FSO performance. The design simulation was carried out using optisystem software for Free Space Optics (FSO) analysis using the FSO MIMO technique in rainy and windy weather in Pekanbaru City. One of the impacts of using the atmosphere as a propagation medium is large attenuation. The variables analyzed by the researchers were the rain variable and the wind variable. If the laser uses power up to 10 mW at a frequency wave of 1550 nm. The simulation results of the four-channel FSO MIMO system are able to provide a maximum beam distance of up to 2 km in rainfall conditions and 8 km in windy conditions. This value was obtained through analysis of the BER and Q-Factor values in the simulation results.Keywords - FSO-MIMO, BER, Optisystem

5G wireless communication technology offers faster data transmission speeds, more stable connections, and greatercapacity and bandwidth compared to previous networks. However, more advanced antenna technology must bedeveloped to overcome propagation and bandwidth problems at mmWave frequencies. The antenna is the maincomponent of the 5G wireless communication system, which uses mmWave frequencies. The purpose of this research isto design a U-slot rectangular microstrip antenna to increase bandwidth at the 26 GHz frequency. The slot-U method onthe rectangular microstrip antenna patch is used to enhance bandwidth. To realize the research method, an antennawas designed without and with a U-slot using analytical calculations, then a simulation was carried out by comparingthe microstrip antenna designs with and without a U-slot, after which an evaluation of the performance of the antennaparameters was carried out. The simulation results show that the U-slot rectangular microstrip antenna design showsan increase in bandwidth, gain, and directivity of 119.14%, 42.66%, and 18.79%, respectively, compared to therectangular microstrip antenna without slots. The U-slot rectangular microstrip antenna design has succeeded inincreasing bandwidth and other performance parameters, so it can be recommended for mmWave 5G applications.

Abstract

WiFi performance is highly dependent on the quality of the antenna as a system for transmitting and receiving electromagnetic signals. A 1×2 microstrip array antenna for 2.4 GHz WiFi applications with truncated corner and partial ground techniques has been successfully designed and simulated. The adjustment of the truncated corner strategy is to cut the four corners in a rectangular shape on the fix side and the fractional ground strategy on the ground plane. The recreation was carried out utilizing CST program. The results showed an increase in antenna performance in terms of return loss, bandwidth, and gain. The designed antenna showed a return loss of -28.57 dB, a bandwidth of 657MHz, and a gain of 6.05 dBi.These results indicate that the combination of array and structural modifications can significantly improve the performance of microstrip antennas for WiFi applications.
