Patent ID: 8229375

Claim:
A transmitting device in a microwave system, comprising a transmit power control module, a radio frequency transmitting module and an adaptive modulation (AM) module, wherein the AM module is configured to determine a switching event of a modulation mode of the microwave system, and send the switching event to the transmit power control module; the transmit power control module is configured to include a switching event receiving unit, a power adjusting unit and a feedback unit, wherein the switching event receiving unit is configured to receive the switching event, and the power adjusting unit is configured to adjust a transmit power of the radio frequency transmitting module according to the received switching event and a preset power control mode, and the feedback unit is configured to feed back a power adjustment complete event to the AM module after the power adjusting unit has completed the power adjustment; and the radio frequency transmitting module is configured to send a microwave signal to a communication peer end by adopting the transmit power adjusted by the transmit power control module, wherein the power adjusting unit is further configured to determine whether the transmit power of the radio frequency transmitting module is larger than a maximum transmit power of a high modulation mode when the switching event is to switch from a low modulation mode to the high modulation mode, and if the transmit power is larger than the maximum transmit power, reduce the transmit power of the radio frequency transmitting module to the maximum transmit power of the high modulation mode, and the feedback unit feeds back the power adjustment complete event to the AM module after completing the power adjustment; or configured to adjust the transmit power of the radio frequency transmitting module according to the power control mode after the modulation mode has been switched according the switching event when the switching event is to switch from the high modulation mode to the low modulation mode.
