Analisis Performansi Relay Aided Berdasarkan Algoritma Iterative Pada Komunikasi D2d Underlaying

Abstract

Abstrak
Pesatnya perkembangan teknologi membuat beban trafik menjadi kurang optimal pada BS. Hal itu, komunikasi Device to Device (D2D) dapat mengatasi pesatnya jumlah CU. D2D mampu melakukan komunikasi antar device tanpa melalui BS, tetapi dalam komunikasi D2D masih membutuhkan daya yang optimal untuk melakukan komunikasi antar device Oleh karena itu, penelitian ini mengusulkan penggunaan relay pada komunikasi D2D dengan alokasi sumber daya berdasarkan algoritma iterative. Kemudian akan di analisis berdasarkan parameter sumrate, spectral efficiency, dan power efficiency. Hasil dari parameter performansi tersebut dibandingkan dengan skema komunikasi half duplex dan full duplex. Pada skema komunikasi D2D menggunakan relay mendapatkan nilai sumrate sebesar 1,486 x 107 bps, spectral efficiency sebesar 14,860 bps/Hz, dan power efficiency sebesar 2,255 x 104. Berdasarkan hasil yang di dapatkan bahwa penggunaan relay menggunakan alokasi sumber daya dengan algoritma iterative dapat mengoptimalkan komunikasi D2D dan jika dibandingkan dengan skema komunikasi half duplex dan full duplex, skema komunikasi relay aided lebih unggul berdasarkan nilai sumrate dan spectral efficiency.

Abstract
The rapid development of technology makes the traffic load less than optimal on the BS. Therefore, Device to Device (D2D) communication can overcome the rapid number of CUs. D2D is able to communicate between devices without going through the BS, but in D2D communication still requires optimal power to communicate between devices . Therefore, this study proposes the use of relays in D2D communication with resource allocation based on an iterative. Then will be analyzed based on the parameters sumrate, spectral efficiency, and power efficiency. The results of these performance parameters are compared with half duplex and full duplex. In the D2D communication scheme using relay value sumrate 1,486 x 107 bps, spectral efficiency is 14,860 bps/Hz, and power efficiency 2,255 x 104. Based on the results obtained that the use of relays using resource allocation with an iterative can optimize D2D communication and when compared with half duplex and full duplexcommunication schemes, relay aided are superior based on sumrate and spectral efficiency.
