Abstract

Meningkatnya jumlah pengguna jaringan nirkabel telah membawa tantangan baru dalam meningkatkan kualitas jaringan nirkabel. Umumnya, peningkatan ini hanya berfokus pada sisi pengirim dan penerima karena lingkungan propagasi dianggap tidak dapat dikendalikan. Namun, salah satu teknologi baru telah membuka jalan untuk menciptakan smart radio environment, yaitu kondisi di mana lingkungan nirkabel menjadi variabel yang dapat dioptimalkan dengan dapat dikendalikan dan diprogram. Teknologi tersebut adalah Reconfigurable Intelligent Surface (RIS). RIS merupakan sebuah permukaan artifisial yang terbuat dari material elektromagnetik yang dapat dikonfigurasi dengan sebuah pengontrol. Setiap elemen pemantul dapat mengatur amplitudo dan fasa dari gelombang yang mengenainya sehingga dapat dipantulkan ke arah yang diinginkan. Sinyal pantulan dapat digunakan untuk menekan interferensi atau menguatkan sinyal dengan memusatkan arah pantulan sinyal. Pada tugas akhir ini akan berfokus pada evaluasi kinerja dari RIS untuk mengamati efisiensi spektrum dengan simulasi menggunakan MATLAB pada sistem SISO. Selain itu, sebagai pembanding, tugas akhir ini akan melihat efisiensi spektrum jika menggunakan relay dan tanpa perangkat bantuan. Dari hasil simulasi ini didapatkan bahwa RIS dapat memberikan efisiensi spektrum yang lebih baik dari relay dan tanpa perangkat dengan menggunakan daya yang minimum dan dapat terus ditingkatkan dengan meningkatkan jumlah elemen yang digunakan pada RIS.

The increasing number of wireless network users has brought new challenges in improving the quality of wireless networks. Generally, these improvements only focus on the sender and receiver sides because the propagation environment is considered uncontrollable. However, one new technology has paved the way for creating a smart radio environment, namely a condition where the wireless environment becomes a variable that can be optimized by being controlled and programmed. This technology is Reconfigurable Intelligent Surface (RIS). RIS is an artificial surface made of electromagnetic material that can be configured with a controller. Each reflecting element can adjust the amplitude and phase of the wave that hits it so that it can be reflected in the desired direction. The reflected signal can be used to suppress interference or strengthen the signal by focusing the direction of the signal reflection. This final project will focus on evaluating the performance of RIS to observe spectrum efficiency with simulations using MATLAB in SISO system. Apart from that, this final project will look at the signal spectrum efficiency using relays and without assistive devices as benchmarks. From the results of this simulation it is found that RIS can provide better spectrum efficiency than relays and without devices by using low power and can continue to be improved by increasing the number of elements used in RIS.
