Abstract : 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. The impact of this technique can be perceived in terms of reduction in memory requirement of FPGA while applying the DPD, as model coefficients can be represented in lower resolution (lesser bits) while maintaining model performance.
