In this paper, we derive a polyphase analysis to determine the optimum filters in a subband adaptive filter (SAF) system. The structure of this optimum solution deviates from the standard SAF approach and presents its best possible solution only as an approximation. Besides this new insight into SAF error sources, the discussed analysis allows to calculate the optimum subband responses and the ...

This study focused on station and dockless systems related to personal mobility sharing services in the midst of which is currently increasing. Based relevant literatures that operating these two tandem was more efficient for urban management, a methodological framework proposed with combination determining service areas based user preference locations potential demand. applied Geumjeong-gu, Bu...
