ABSTRACT:
Diversity control section111calculates received amplitude levels of all subcarrier signals from all branches, and selects a branch providing the largest amplitude level for each subcarrier signal. Based on the above selection result, selectors104are switched to transmit respective subcarrier signals from the selected branch, and selectors112are switched to receive respective subcarrier signals from the selected branch.
