Abstract

ABSTRAK Sistem komunikasi kooperatif device-to-device (D2D) merupakan salah satu strategi peningkatan kecepatan data dan efisiensi energi. Pada sistem kooperatif, mekanisme relay merupakan faktor penting dalam meneruskan informasi. Model jaringan merupakan isu penting untuk meningkatkan kecepatan, kinerja dan efisiensi energi pada sistem. Oleh sebab itu, makalah ini menganalisis kinerja jaringan hybrid kooperatif D2D pada teknologi 5G menggunakan teknik pemilihan relay reaktif atau reactive relay selection (RRS). Beberapa parameter kinerja penting telah simulasikan, seperti model jaringan, SNR, BER dan throughput. Hasil simulasi menunjukkan bahwa jaringan kooperatif hybrid-relay dengan RRS menghasilkan nilai BER yang lebih kecil dan throughput yang lebih tinggi dibandingkan model multi-relay dan multi-hop relay. Dengan demikian, jaringan hybrid-relay dengan pemilihan relay lebih efisien dibandingkan jaringan lainnya. Kata kunci: sistem komunikasi kooperatif, pemilihan relay reaktif, multi-hop, multi-relay, hybrid-relay. ABSTRACT A device-to-device (D2D) cooperative communication system is one of the strategies to increase data speed and energy efficiency. In a cooperative system, the relay mechanism is an important factor in forwarding information. A network model is an important issue to increase the speed, performance and energy efficiency of the system. Therefore, this paper analyzes the performance of D2D cooperative hybrid networks on 5G technology using reactive relay selection (RRS) techniques. Some important performance parameters have been simulated, such as network models, SNR, BER and throughput. Simulation results show that hybridrelay cooperative networks with RRS produce smaller BER values and higher throughput compared to multi-relay and multi-hop relay models. Thus, hybridrelay networks with relay selection are more efficient than other networks. Keywords: cooperative communication system, reactive relay selection, multihop, multi-relay, hybrid-relay.

Abstract

Abstract. The development of information and communication technology is growing rapidly, particularly in the transmission of digital information. The process of transmitting digital information through the communication channel will be interferenced by noise, distortion and multipath fading so that the information is likely to experience an error or incorrect detection at the receiver, which can decrease the system performance. This research proposes the design and simulation of encoder-decoder based on the number nine to transmit digital information reliably and precisely. The goal of this research is to design and simulate the encoder decoder as a scheme of error detection and correction and to reduce bit error rate that occurs during the process of transmitting digital information. The research method uses design and computer simulation where the encoder-decoder is modeled mathematically, design is structured and a computer simulation is developed for the performance of encoder-decoder based on the number nine in the transmission of digital information. The result of this research shows that the proposed encoder-decoder can detect the errors transmission and correct the errors at receiver.Keywords: Digital information, encoder-decoder, coding scheme, and transmission information. Abstrak.

Abstract

OFCDM is an attractive multiple access scheme for high data rate application in Fourth-generation (4G) wireless communication system. Previously, several researches were only investigated the performance of OFCDM based on variable spreading factor. However, there are several system parameters may affected the performance of OFCDM. Therefore, this paper investigates the impact of several parameters on the performance system of OFCDMA over Rayleigh Fading channel as a realistic channel in wireless communications.The simulation system model of OFCDM is introduced. The computer simulation is developed by using MATLAB programming in order to show the impact of several parameters for OFCDM’s performance including number of carriers, size of symbol, symbol rate, bit rate, size of guard interval and spreading factor. The simulation results show that the higher number of carriers, larger size of symbol, higher symbol rate, higher bit rate and larger spreading factor are giving the better system’s performance in terms of Bit Error Rate (BER). However, the larger guard interval is giving the worst system’s performance.So all the parameters should be considered in the implementation of OFCDM for the 4G wireless communication system. DOI: http://dx.doi.org/10.11591/telkomnika.v10i3.621

Abstract

Future wireless communications technology should fulfill the demands of multimedia applications, interactive internet service, high data rates and power efficiency. However, wireless channel is affected by multipath fading that can degrade the system performance. To overcome the problem, cooperative communication has been introduced to be an efficient diversity technique to combat the multipath fading, to improve capacity and the system performance, and to reduce the energy comsumption by using power allocation technique in the network. This paper proposes an optimized power allocation (OPA) for cooperative amplify-and-forward (AF) protocol with convolutional codes (CC). A computer simulation model for the proposed system is developed using Matlab programming.  Then, performance of the system is evaluated in terms of the system throughput, bit error rate and amplification coeficient for power allocation. Furthermore, the different rates of CC are also considered in the network. Simulation results show that multi-relay AF network can provide a higher throughput and lower bit error rate. Moreover, the performance of OPA system is better than that of non-OPA system. The using lower rate of CC in the OPA system provides coding gain for multi-relay cooperative AF network. Finally, the different amplification coeficients among relays give a significant improvement to optimize the system performance.

Abstract

Rapid assessment is part of disaster emergency response that are covering quick and precise assessments to the calamity place, casualties and damaged building. So far, rapid assessment in BPBD Aceh Barat is still conducted manually without an information system within its management of disaster emergency response. To support a successful result in emergency response activity, designing an android based rapid assessment application system is demanded to facilitate the public users (community/volunteer) and trained users (TRC Team) of BPBD Aceh Barat. Research methods of the study was based on Perka BNPB and previous studies. Then, continued by building prototype, and users System Usability Scale test. This research result is an android based rapid assessment application. The procedure is by inputting data by user via Android application that contained disaster info, casualties, refugee data, building damage, volunteer and humanitarian logistic. Then validated at www.tdb-aceh.com. Users can access to news and information, BNPB regulations, important dials, and TRC BPBD members on application. SUS test results showed that public users of 12 respondents average score is 68,95 and trained users of 3 respondents average score is 67,5. Analysis to both respondents group showed that the application is well-integrated, user friendly, and easy to understand.
