This paper investigates the issues related to numerical stability and complexity of models for multi-carrier and carrier aggregated transmitted signal using wideband power amplifier and proposes independent component analysis (ICA) technique as a solution. It has been reported that ICA provides better numerical stability and lower dispersion of coefficients in established polynomial based models....
Waveform engineering is commonly used to optimize the power efficiency, linearity and output power of power amplifiers (PA). In this search for the optimal waveforms, PA designers have become interested in knowing the internal mode of operation of the device at the current-source reference-planes. However given the huge search space for the input and output multi-harmonic terminations required to...
