ABSTRACT:
An apparatus and method for transmission power amplifier bias control in an enhanced data rate for global system mobile evolution mobile communication device. The apparatus can include a transmitter configured to transmit information on an enhanced data rate for global system mobile evolution network at a first transmitter output power. The transmitter can include a modulator configured to receive an input signal and map information in the input signal to symbols represented by eight phase offsets and a power amplifier configured to provide the first transmitter output power for transmitting the symbols represented by eight phase offsets. The apparatus can also include a controller configured to adjust a first bias condition of the power amplifier to a second bias condition based on a changed parameter of operation related to the data stored in a memory.
