Abstract
The complex gain baseband adaptive predistorter is flexible and practical. However, it´s quite sensitive to errors in the linearization system. This paper analyzes and simulates the effect of errors in feedback path on linearization performance, and presents the protective considerations in algorithm design to ensure the convergence of the adaptation. The simulation results demonstrate that protection in algorithm can effectively eliminate the effect of errors.
