Abstract :
Performance calibration of lineariser schemes designed to offset the impairments arising through high power amplifier (HPA) nonlinearities is addressed in this paper. Relating to the importance of linearisation in future reconfigurable ultra wideband (UW) mobile wireless communication systems, the benefits of the percentage linearisation area (PLA) measure is illustrated through EVM calculations (´simulation measurements´) of an appropriate test signal after its passage through a typical HPA without linearisation and with varying degrees of linearisation.
