BASE STATION EQUIPMENT USING DIVERSITY RECEPTION

摘要

A base station in a duplex radio communication system comprises two transceivers (10, 12) each of which has a transmitter (14, 20), a main receiver (16, 22) and a diverse receiver (18, 24). A main antenna (26) is connected to the common port of a first diplex filter (38), and a diverse antenna (28) is connected to the common port of a second diplex filter (40). A first amplifier and splitter (30, 32) feed main receive signals from the main antenna (26) to the main receivers (16, 22) and a second amplifier and splitter (34, 36) feed diverse receive signals from the diverse antenna (28) to the diverse receivers (18, 24). The diverse antenna (28) acts not only as a receive antenna, but also transmits signals from the transmitter (20), so more power is available for transmission.
