    Abstract: A technique for performing adaptive predistortion in a transmitter includes receiving, at a first input of an error signal unit, a delayed version of a baseband input signal. The technique also includes receiving, at a second input of the error signal unit, a power amplifier feedback signal from an output of a power amplifier. An input error signal that corresponds to a difference between the delayed version of the baseband input signal and the power amplifier feedback signal is then provided at an output of the error signal unit. The input error signal is then received at an input of a signal conditioner. An adjusted error signal that has a lower direct current offset than the input error signal is provided at an output of the signal conditioner.

    Abstract: Embodiments include methods and apparatus for performing transmit power control. A gain application element receives a sequence of digital input samples and a digital gain signal, and combines the digital gain signal with the digital input samples to generate a sequence of gain-compensated digital samples. A power amplifier receives and amplifies an analog version of the gain-compensated digital samples in order to generate an antenna output signal. A feedback path generates an analog feedback signal from the antenna output signal, produces a sequence of digital feedback samples from the analog feedback signal, and generates difference values based on the digital feedback samples. When a specified type of constant modulus symbol is represented in the antenna output symbol, the feedback path accumulates the difference values into an accumulated error value, and produces the digital gain signal from the accumulated error value.
