CENTRALIZED ADAPTOR ARCHITECTURE FOR POWER AMPLIFIER LINEARIZATIONS IN ADVANCED WIRELESS COMMUNICATION SYSTEMS

摘要

Embodiments of a centralized predistortion system and corresponding adaptive predistortion processes are disclosed. In general a central node includes one or more centralized predistortion components that enable predistortion for one or more remote transmit chains in order to compensate for non linearity of power amplifiers in the one or more remote transmit chains. For instance in one embodiment the central node is a hub base station and the one or more remote transmit chains are included in one or more transmitters at one or more satellite base stations.
