IN-BUILDING DISTRIBUTION REPEATING SYSTEM BY USING DIGITAL SIGNAL PROCESSING

摘要

PROBLEM TO BE SOLVED: To provide a premises wireless distributed relay system using a digital signal processing that can improve communication quality and retransmit quality signals.

SOLUTION: The premises radio distributed relay system using a digital signal processing improves communication quality and retransmits a good quality signal, by eliminating undesired interference signals contained in high-frequency signals by a digital signal processing part, after converting the high frequency signal received from a base station or a communications system through a wired or wireless connection into a digital signal and connecting a plurality of expansion units with a remote unit through an inexpensive communication line.
