摘要:
A half-duplex mobile terminal having first and second receiver branches connected, during a receive mode, to respective antennas, is disclosed. One of the antennas is selectively connected to the first receiver branch or to a transmitter circuit. The first antenna is connected to the first receiver branch during a first interval, during which interval data is detected using outputs from both the first and second receiver branches. The first antenna is disconnected from the first receiver branch at the end of the first interval, and, during a second interval immediately following the first interval, data is detected using the output of the second receiver branch. A portion of the incoming transmission that arrives during the transition between the receive mode and transmit mode in a half-duplex transceiver is thus received and detected, improving performance of the half-duplex transceiver.
