DISTORTION SUPPRESSING REPEATER FOR IMPLEMENTING SHORT DELAY, PARTICULARLY FOR REDUCING THE NUMBER OF TIMES OF FREQUENT HANDOFF IN AN AREA WHERE BASE STATION SIGNALS OVERLAP AND EFFECTIVELY USING A RAKE RECEIVER OF A MOBILE STATION

摘要

PURPOSE: A distortion suppressing repeater for implementing a short delay is provided to enhance speech quality by preventing degradation of a signal due to fine distortion caused by an antenna separation degree. CONSTITUTION: When a signal is inputted to a circulator(601), it is inputted to a duplexer(602) through a band separation filter(604) according to directionality characteristics of the circulator(601). Then, the signal passes pass bands of the duplexer(602) according to the direction of the circulator(601) and then dies off through a dummy(603). At this time, the signal is reflected by a reflection band of the duplexer(602), proceeds toward the number(605) of the circulator(601) according to proceeding characteristics of the circulator(601), passes through a filter(606), and then outputted with a certain waveform. Namely, because the waveform outputted through the number(607) has the form of band pass, a band pass filter with a short delay can be implemented.
