A TWO-WAY PAGING SYSTEM AND APPARATUS A TWO-WAY PAGING SYSTEM AND APPARATUS

摘要

A paging network having at least one paging transmitter and receiver site (Base 1) for transmitting paging messages and for receiving acknowledgments, the paging network, comprising: a timing control unit for timing said paging transmissions and for activating receive processing channels; a plurality of directive antennas (80) coupled to associated receive signal processing means for receiving signals from respective antennas and converting said signals to corresponding complex numerical samples at times determined by said timing control unit; a memory for storing said complex numerical samples; and processing means (81) for processing said complex numerical samples from respective antenna elements (80) in a plurality of ways corresponding to different possible directions and times of arrival of said acknowledgments from a plurality of said pagers in order to improve detection of said acknowledgments.
