Hammerstein-Like Predistortion Techniques for Wideband Wireless Power Amplifier Linearization

In this paper, a novel Hammerstein-like predistortion technique is proposed to linearize the wideband wireless power amplifiers. This Hammerstein-like predistortion technique is based on a Hammerstein-like block configuration, including a memoryless strong nonlinear block followed by a dynamic weak nonlinear block. Here the memoryless strong nonlinear block is utilized to account for the static memoryless nonlinear property, and the weak nonlinear block is employed to eliminate the memory effects. The validation results demonstrate the superiority of the proposed Hammerstein-like predistortion technique in suppressing the memory effects in comparison to a traditional one.
