Patent ID: 8798559

Claim:
A transmitter comprising: a power amplifier configured to amplify a power amplifier input signal to output a power amplifier output signal; a predistortion sub-system configured to effect predistortion of the power amplifier input signal to compensate for non-linearity of the power amplifier and memory effects, the predistortion sub-system comprising: a memory-less predistortion component configured to compensate for the non-linearity of the power amplifier; an Infinite Impulse Response filter configured to compensate for long-term memory effects; and a Finite Impulse Response filter configured to compensate for short-term memory effects, wherein the memory-less predistortion component, the Infinite Impulse Response filter, and the Finite Impulse Response filter are configured in series; and an adaptation sub-system configured to adaptively configure the predistortion sub-system.
