Selective linearization of scalable fault tolerant frequency agile transmitters

Abstract:

Apparatus and method for selective linearization of scalable fault tolerant frequency agile transmitters. In one embodiment, the method includes receiving timestamped carrier configurations and segmenting the timestamped carrier configurations into time segments having a pre-determined time length. The method also includes determining composite carrier configuration in a present time segment for a predetermined number of future time segments and determining a correction solution of a plurality of correction solutions associated with the composite carrier configuration in a mapping of a plurality of carrier configurations and the plurality of correction solutions. The method includes providing the correction solution to a linearizer of at least one of a plurality of multi-carrier power amplifiers. The plurality of power amplifiers are provided in one or more banks of multi-carrier power amplifiers.
