Abstract
Perkembangan teknologi dan mobilitas user yang sangat tinggi
mengakibatkan kebutuhan akan sinyal yang kuat serta jangkau yang luas
juga meningkat. Namun jika hanya memperluas coverage sinyal saja hal
tersebut tidak akan terlalu efektif jika user hanya memiliki
kecendurungan mobilitas yang tinggi pada suatu arah tertentu, sehingga
diperlukan teknologi yang dapat menjangkau pergerakan user pada area
tersebut. Teknologi antena cerdas (smart antenna) merupakan salah satu
solusi untuk menyelesaikan permasalahan tersebut. Smart antenna
merupakan suatu antena dengan konfigurasi beberapa susunan elemen
yang dapat mengenali tanda spasial sinyal seperti arah kedatangan sinyal
dan mengarahkan beam pada suatu sumber sinyal yang dalam keadaan
diam ataupun bergerak.
Dalam tugas akhir ini dilakukan implementasi teknologi smart
antenna pada Universal Software Radio Peripheral (USRP) untuk
deteksi arah kedatangan sinyal. Spesifikasi sistem yang dibangun yakni
menggunakan Algoritma MUSIC untuk deteksi arah kedatangan sinyal
dan Algoritma Maximum Signal to Interference untuk beamforming
sinyal. Implementasi dilakukan dengan menggunakan 5 unit USRP yang
bekerja pada frekuensi 2,4 GHz. Pemrograman dan simulasi kedua
algoritma dilakukan dengan menggunakan software Matlab dan untuk
menerapkan algoritma tersebut pada USRP digunakan software
LabVIEW.
Hasil simulasi algoritma dengan menggunakan Matlab diperoleh
error sudut rata-rata sebesar 0o dan dari hasil pengukuran dilapangan
diperoleh tingkat akurasi deteksi arah kedatangan dengan error sudut
rata-rata yang terkecil adalah sebesar 19,96 o.

Developments in technology and user high mobility are causes the
need for strong signal as well as the extensive range also increased.
However, if only expand signal coverage alone it would not be very
effective if the user only has the tendency in a high mobility in a
particular direction, so that the necessary technology that can reach the
user movement in these areas.Smart antenna technology is one of the
solutions to solve these problems. Smart antenna is an antenna with
several sets of configuration elements that can recognize signs of spatial
signal such as direction of arrival signal and directs the beam to a
signal source in rest or moving condition.
In this final project the implementation of smart antenna
technology to Universal Software Radio Peripheral (USRP) for the
detection of the direction of arrival of a signal. Specification of the
system built using MUSIC algorithm for the detection of the direction of
arrival of a signal and Algorithm Maximum Signal to Interference for
beamforming signal. Implementation is done using 5 units of USRP who
works at a frequency of 2.4 GHz. Programming and simulation of both
algorithms performed using Matlab software and to implement the
algorithm on USRP used LabVIEW software.
The simulation results using Matlab algorithm obtained angle
error average of 0° and the results obtained in the field of measurement
accuracy rate detection angle direction of arrival with an average error
smallest is at 19.96 o.
