"ABSTRAK
Pada tugas akhir ini, saya menganalisa probabilitas outage dari teknologi full-duplex dengan menggunkan sistem MIMO (2x2) dengan memperhatikan faktor dari self-interference. Faktor self-interference pada tugas akhir ini diasumsikan telah ditekan dengan menggunakan active dan passive cancellation. Diasumsikan kanal yang dilalui sinyal antar 2 node merupakan kanal Rayleigh dan kanal yang dilalui sinyal interferensi merupakan kanal Rician. Selanjutnya, akan diperhatikan nilai dari probabilitas outage akibat dampak dari perubahan faktor K, 𝛾̅ɑ adalah SINR (Signal to Interference plus Noise Ratio), threshold rate (R) dan jumlah antena (N). Pada hasil perhitungan dengan nilai dari K = 35 dB atau lebih serta SINR = 70 dB dan R = 10 bps/Hz, probabilitas outage bernilai lebih dari 10-2 namun, dengan nilai SINR = 70 dB dan R = 10 bps/Hz, probabilitas outage bernilai lebih kecil dari 10-4 untuk nilai K = 15 dB atau kurang, maka didapat bahwa probabilitas outage meningkat jika nilai K meningkat. Selanjutnya, dengan nilai K = 10 dB didapat nilai dari probabilitas outage sebesar 10-4 ketika nilai SINR = 60 dB dan probabilitas outage sebesar 10-6 ketika nilai SINR = 70 dB, maka didapat probabilitas outage menurun jika nilai SINR meningkat. Hasil perhitungan lainnya dengan nilai K = 10 dB, didapat nilai dari probabilitas outage lebih dari 0,2 ketika nilai R = 6 bps/Hz dan probabilitas outage sebesar 0,8 ketika nilai R = 8 bps/Hz, didapatkan Probabilitas outage meningkat jika nilai R meningkat. Selanjutnya, dengan nilai K = 15 dB dan R = 20 bps/Hz, didapatkan nilai probabilitas outage sebesar 0,4, namun ketika nilai dari K = 15 dB dan R = 20 bps/Hz, nilai dari probabilitas outage dibawah 0,1, maka probabilitas outage menurun jika nilai N meningkat.

ABSTRACT
In this report, I analyze an outage probability in bidirectional nirkabel communication using full-duplex MIMO system with consider effect of self-interference. The self-interference in this report is mitigated by active and passive cancellation, yet there is still interference happens in this system, called residual interference. Assumed, transmit information signal (channel between node-1 and node-2) using Rayleigh fading channel and express interference signal stream using Rician fading channel. I derive a closed-form solution of outage probability towards effect of Rician factor (K), γ̅ɑ is SINR (Signal to Interference plus Noise Ratio), threshold rate (R) and number of antenna (N). With SINR is 70 dB and R is 10 bps/Hz, value of outage probability is more than 10-2, yet with SINR is 70 dB and R is 10 bps/Hz, we get value of probability is below 10-2 for value of K is 15 dB or below, we obtain that value of outage probability increases when we increasing value of K. At value of K is 10 dB, we get outage probability is 10-4 when SINR is 60 dB and outage probability is 10-6 when SINR is 70 dB, from the result we conclude that for certain value of R, as SINR increases outage probability decreases for given K. Furthermore, at value of K is 10 dB, we get outage probability is more than 0.2 when R is 6 bps/Hz and outage probability is 0.8 when R is 8 bps/Hz. We get that as threshold rate increases outage probability increases for given SINR. Moreover, at value of K is 15 dB and R is 20 bps/Hz, we get outage probability is 0.4 but when value of K is 15 dB and R is 20 bps/Hz, we get outage probability is below 0.1. We obtain that increases number of antenna will decreases value of outage probability."

"Peningkatan trafik mobile data di Indonesia diprediksi oleh CISCO akan meningkat sebesar 12 kali lipat pada tahun 2020. Trafik tersebut diprediksi akan terus bertambah dengan meluasnya pemanfaatan teknologi IoT secara masif sebagai salah satu tren teknologi masa depan. Pemanfaatan teknologi IoT di Indonesia digunakan untuk mendukung program smart city di berbagai kota dan diperkirakan akan berimplikasi pada kenaikan trafik. Sementara itu, Indonesia diperkirakan akan kekurangan spektrum mobile broadband sebesar 500 MHz pada tahun 2020. Implementasi teknologi IoT untuk mendukung smart city diperkirakan akan memperbesar defisiensi spektrum tersebut. Hingga saat ini belum ada penelitian yang menghitung prediksi jumlah kebutuhan spektrum untuk layanan IoT di Indonesia. Forum bersama industri elektronik di India IESA TIE IoT Forum telah melakukan prediksi jumlah kebutuhan spektrum untuk layanan IoT. Dalam rangka mendukung program pengembangan smart city di India, IESA TIE IoT Forum merekomendasikan alokasi spektrum tambahan sebesar 10 ndash; 20 MHz spesifik untuk layanan IoT. Penelitian ini bertujuan untuk menghitung prediksi kebutuhan spektrum untuk layanan IoT dengan studi kasus Jakarta Smart City menggunakan metode perhitungan yang digunakan oleh IESA TIE IoT Forum. Hasil penelitian ini adalah kebutuhan spektrum untuk layanan IoT meningkat 17,27 dalam kurun waktu 2016-2021 dengan kebutuhan spektrum sebesar 18,67 MHz untuk skenario 1 dan 19,91 MHz untuk skenario 2. Kebutuhan spektrum tersebut dapat diantisipasi oleh regulator dengan memperhatikan ketersediaan alternatif spektrum saat ini, peluang industri dan inovasi IoT dalam negeri serta kebutuhan regulasi terkait IoT seperti standarisasi perangkat, harmonisasi spektrum dan sistem keamanan data.

In Indonesia, mobile data traffic is predicted by CISCO will increase significantly by 12 times in the period of 2015 ndash 2020. The traffic is predicted will grow continuously by widespread utilization of IoT technologies on a massive scale as one of the future technology. IoT is used to support the smart city program in various cities in Indonesia and expected to have implications in traffic growth. Meanwhile, Indonesia is expected to experience deficiency of 500 MHz spectrum for mobile broadband services in 2020. IoT implementation to support smart city is predicted to enlarge spectrum deficiency. There has been no study which calculates spectrum needs for IoT services in Indonesia. Electronics industrial collaboration forum in India IESA TIE IOT Forum has made predictions of spectrum need for IoT services. In order to support smart city in India, IESA TIE IoT forum proposed to allocate additional spectrum of 10 ndash 20 MHz specific for IoT services. This research aims to calculate spectrum need for IoT services in case of Jakarta Smart City. The results are spectrum need for IoT services increase by 17.27 in the period of 2016 ndash 2021 with the spectrum needs of 18.67 MHz for scenarios 1 and 19.91 MHz for scenarios 2. The spectrum needs should be anticipated by regulator to consider the availability alternative spectrum, opportunity and innovation IoT industry in Indonesia and the needs of regulations related to IoT for instance standardization of devices, spectrum harmonization and data security systems."
