Abstract
A wireless subscriber communication unit comprises a transmitter having a power amplifier and a feedback power control loop having a power control function arranged to set an output power level of the power amplifier. The power control function is arranged to perform a back-off of the output power prior to completion of a transmission burst.
Claims20
A wireless subscriber communication unit comprises a transmitter comprising:
- a power amplifier;
- and
- a closed loop analog feedback power control loop having a power control function arranged to set an output power level of the power amplifier,
- wherein the power control function performs a back-off of the output power level, in response to a back-off of a power level provided to the power amplifier, prior to completion of a transmission burst.
A method of power control in a wireless subscriber communication unit comprising a transmitter having a closed loop analog feedback power control loop having a power control function, the method comprising the steps of:
- setting an output power level of the transmitter by the power control function;
- transmitting a data burst;
- and
- performing a back-off of the output power level, in response to performing a back-off of a power level provided to a power amplifier, prior to completion of a transmission burst by the power control function.
An integrated circuit for use in a wireless communication device comprising:
- a transmitter;
- a closed loop analog feedback power control loop having a power amplifier;
- and
- a power control function arranged to set an output power level of the transmitter, wherein the power control function performs a back-off of the output power level, in response to a back-off of a power level provided to the power amplifier, prior to completion of a transmission burst.
