摘要：

This paper investigates the application of genetic algorithms to PA linearization using digital pre-distortion with narrowband feedback. An algorithm is presented that adapts a polynormal pre-distortion function to minimize adjacent channel emissions. The paper describes the implementation of, this algorithm and compares its performance with a random search technique. Results show nearly optimal performance in a limited number of iterations, suggesting that this technique can be employed as a low-cost solution to meet ACLR requirements.
