Digital Predistortion Technique for MIMO Transmitters
The Journal of Korea Information and Communications Society, 2012 An adaptive digital predistortion (PD) technique is proposed for linearization of power amplifiers (PAs) in multiple-input multiple-output (MIMO) transmitters. We consider a PD structure equipped with only one combined feedback path while conventional systems have multiple feedback paths.
