Segmented Statistical Error-Based Adaptive Method for Linearization of Power Amplifiers

In this letter, we present an adaptive method for linearizing radio frequency (RF) power amplifier (PA). The input and output error is segmented in light of the signal magnitude to improve the convergence speed of the linearizer's parameter optimization. The feedback bandwidth and the sampling...
