Abstract
Metode estimasi parameter Space Alternating Generelized Expectation-
Maximization (SAGE) , mengestimasi parameter subspace yang terdiri dari
Directional Of Arrival (DOA) dan Directional of Departure (DOD), dan parameter
temporal yang terdiri dari Delay dan Amplitudo Kompleks. SAGE diterapkan
dengan mengestimasi parameter sudut terlebih dahulu kemudian dilanjutkan
dengan parameter temporal secara berurutan, hal ini dilakukan untuk pengukuran
dengan perangkat resolusi delay yang rendah.
Hasil simulasi diterapkan pada antena array planar dan antena array linier,
yang dinyatakan dengan metode RMSE. Hasil simulasi tersebut menunjukkan
bahwa kinerja SAGE dalam menndeteksi parameter yang dimulai dari sudut lebih
baik dibandingkan dengan kinerja SAGE yang mendeteksi parameter yang dimulai
dari delay. Sedangkan hasil verifikasi SAGE dilakukan dengan pengukuran di
Gedung Baru Hall PENS dengan menggunakan perangkat USRP dan antena array
linier, dimana hasil estimasi delay didapatkan dari hasil crosscorelasi antara data
yang diterima dan data yang dikirim yang selanjutnya terdapat 3 komponen sinyal
yang terdeteksi hal ini disebabkan oleh resolusi perangkat yang rendah. Selain itu,
SAGE mampu mengindentifikasi arah keberangkatan dan arah kedatangan dari 3
komponen sinyal tersebut. Arah keberangkatan dan arah kedatangan yang
merupakan output dari SAGE, divalidasi ulang menggunakan Ray Tracing 2 D
yang merupakan gambaran penjajakan sinyal berdasarkan lokasi pengukuran. Hasil
validasi antara output SAGE dan Ray Tracing mempunyai selisih eror sekitar 36°.

Alternating Space parameter estimation method Generelized Expectation-
Maximization (SAGE), estimating the parameters subspace consisting of Directional Of
Arrival (DOA) and Directional of Departure (DOD), and temporal parameters consisting
of Delay and Amplitude Complex. SAGE is applied to estimate the parameters of the corner
first and then proceed with the temporal parameters sequentially, this is done to measure
the delay that low-resolution devices.
The simulation results applied to a planar antenna array and linear array antenna,
which is expressed by the method of RMSE. The simulation results show that the
performance of SAGE detect parameters which starts from the point better than the
performance of SAGE that detect parameters which starts from the delay. While the results
of the verification is done by measuring SAGE in New Building Hall PENS using USRP
devices and linear array antenna, in which the estimation results obtained from the
crosscorelasi delay between the received data and the subsequent data sent, there are 3
components of the detected signal caused by the resolution of this case Low devices. In
addition, SAGE is able to identify the direction of departure and arrival directions of the
three components of the signal. Direction of departure and arrival direction which is the
output of SAGE, revalidated use Ray Tracing 2 D which is a picture based on the location
of the measurement signal assessment. Validation results between SAGE and Ray Tracing
output has an error margin of about 36 °.
