Abstract
A training sequence and digital linearization process for a power amplifier are provided. In particular, a system for maintaining linear operation of an amplifier is includes an estimation component configured to determine compensation coefficients. The system further includes a digital pre-distorter configured to compensate for non-linear operation of the amplifier based on the compensation coefficients. The compensation coefficients are determined based on a training sequence signal having a time synchronization portion and a linearization sequence portion.
