Updated nonlinearity models for solid-state power amplifiers (SSPAs) include both amplitude and phase distortions, and thus being the same as nonlinearities in traveling-wave tube amplifiers (TWTAs), resulting in detrimental effects for multiple-input multiple-output space-time block code (MIMO-STBC) systems with nonlinear amplifications. This work presents a thorough investigation for the performance...
Based on thorough analyses of adverse effects from nonlinear distortion caused by high power amplifiers (HPAs) with phase conversion in multiple-input multiple-output space-time block code (MIMO-STBC) systems, this work proposes a nonparametric phase estimation and compensation method for the received signal. Using the optimal feedforward blind estimation technique, the receive signal's rotated phase...
