Abstract

Standar penyiaran televisi digital yang ditetapkan di Indonesia adalah Digital Video Broadcasting-Terrestrial Second Generation (DVB-T2). Di dalam sistem DVB-T2 terdapat jaringan Single Frequency Network (SFN) yang dapat menjadi alternatif perencanaan jaringan selain jaringan Multiple Frequency Network (MFN). Jaringan SFN menghasilkan efisiensi spektrum frekuensi serta peningkatan kualitas layanan karena distribusi yang lebih homogen dari kuat sinyal yang diterima pada area cakupan. Namun demikian, dalam prakteknya beberapa daerah juga akan menunjukkan degradasi. Untuk meningkatkan kinerja SFN, standar sistem DVB-T2 terdapat mekanisme teknik diversity MISO (Multiple Input Single Output). Teknik ini digunakan untuk menghasilkan SFN gain yang lebih optimal. Salah satu faktor yang mempengaruhi SFN Gain adalah faktor Power Imbalance (PI). Pada tugas akhir ini akan dilakukan evaluasi nilai SFN Gain khususnya di Wilayah Gerbangkertasusila dari beberapa skenario penerapan, termasuk membandingkan mekanisme SISO dengan MISO. Hasil simulasi menunjukan bahwa nilai CNR pada skema SISO lebih tinggi dibandingkan skema MISO, yaitu 51.63 dB pada skema SISO dan 51.33 dB pada skema MISO. Pada wilayah Surabaya, Kecamatan Driyorejo Gresik, dan Kecamatan Kembang Lamongan memiliki nilai CNR MISO dan SISO melebihi nilai rata-rata keseluruhan semua daerah. Hasil evaluasi SFN Gain menunjukan pada 21 kombinasi MISO, 13 kombinasi mengalami degradasi, sedangkan 8 kombinasi lainnya (Kombinasi 6, 11, 14, 15, 18, 19, 20, 21) beberapa daerah mengalami SFN Gain. Dari 8 kombinasi ini dapat disimpulkan diperlukan jarak minimum antar pemancar, yaitu sebesar 18.09 km untuk dapat menghasilkan SFN gain. ========================================================================= Digital television broadcasting standards in Indonesia is the Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2). In the DVB-T2 system there is a network of Single Frequency Network (SFN) SFN is network planning alternative other than Multiple Frequency Network (MFN). SFN network provide spectrum efficiency as well as improvement the quality of services as a more homogeneous distribution of the received signal strength in the area of coverage. However, in practice some areas will also show degradation. In order to improve the performance of the SFN operation, the second generation broadcast system DVB-T2 standard incorporates multiple input single output (MISO) antenna diversity mechanisms This technique is used to produce a more optimal SFN gain. SFN gain can be affected by factors Power Imbalance (PI). In this final project will be evaluating SFN Gain value in Gerbangkertasusila especially in the region of several application scenarios, including compared the SISO mechanism with MISO. Results show that CNR at SISO scheme is higher than MISO scheme, which is 51.63 dB at SISO scheme and 51.33 dB at MISO scheme. Surabaya, Driyorejo Gresik, and Kembang Lamongan has an average CNR higher than the overall average CNR for SISO and MISO scheme. Evaluation SFN Gain results showed the 21 combination of MISO, 13 combination degraded, while eight other combination (combination of 6, 11, 14, 15, 18, 19, 20, 21) some areas had SFN gain. From this combination it can be concluded required minimum distance between the transmitter at 18.09 km to produce SFN gain.
