Abstract

In this letter, two basis function multiplexing-based behavioral modeling methods for digital predistortion (DPD) of RF power amplifiers (PAs) are proposed to reduce the running complexity of DPD. The proposed full basis-propagating selection (FBPS) model and reduced-complexity FBPS (RC-FBPS) model give two reasonable ways to multiplex even-order basis functions, extending the basis-propagating selection (BAPS) model which only uses basis function delay and odd-order basis functions. The experimental results confirm that both the proposed FBPS and RC-FBPS models can achieve a good tradeoff between running complexity and performance.

射频功率放大器数字预失真的低运行复杂度模型

本文提出了两种基于基函数复用的射频功率放大器数字预失真行为建模方法，以降低数字预失真的运行复杂度。所提出的全基传播选择（FBPS）模型和降复杂度FBPS（RC-FBPS）给出了两种合理的偶阶基函数复用方法，扩展了只使用基函数延迟和奇阶基函数的基传播选择模型。实验结果证实，所提出的FBPS和RC-FBPS模型都可以在运行复杂性和性能之间实现良好的折衷。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
