This paper studies the performance of a memoryless power amplifier (PA) linearization technique based on a probabilistic approach. This technique employs a nonparametric method to derive a predistorter function, which does not need any parametric modeling and explicit parameter estimation. It only needs to calculate a probabilistic cumulative distribution function (CDF) and a quantile function (an...
In communication systems employing multiple beam antennas, multi-port amplifiers (MPA) offer a flexibility of allocating/moving power or capacity among beams easily, to maximize the usage of the total capacity available, assuming that power amplifiers (PA) are linear. In this paper, we show that when the PAs are nonlinear, the MPA performance is severely limited due to the PAspsila nonlinearity, and...
In this paper, we investigate the effects of nonlinear power amplifiers in a multi-port amplifier subsystem, and the benefit resulting from applying a type-based linearization approach. Computer simulations show that power efficiency and system performance can be significantly improved by linearizing the power amplifiers.
