YAMAZAKI Takato (OHNO Kohei laboratory), a second year student of the master’s course on the Network Design Program, Graduate School of Advanced Mathematical Sciences, won the Student-Session Presentation Award at the Technical Conference on Communication Systems, IEICE.
This award is intended to encourage active presentations by students in the field of communication systems and is given to students who delivered distinguished presentations in the student-award session at the Technical Conference on Communication Systems, IEICE.
Title of the awarded presentation: An Improvement Method of Arrival Path Power Prediction for Millimeter-wave Using LSTM Under Indoor Environments
This presentation examines the prediction of power received through the first arrival path of millimeter-wave indoor. Assuming that a user walks indoors, properties of the transmission path are acquired. From measurements, power received through the first arrival path is obtained from impulse response. Then, power to be received at the position ahead of the current position of the user is predicted by LSTM (Long Short Term Memory). On the other hand, values of received power obtained by the experiment vary more than actual values. Therefore, by using average values at several previous steps as the learning data, predictions are less affected by variation, and its accuracy can be improved. It shows that this method enables prediction of power received at even farther positions.
