What is DPD (digital predistortion)?

Digital Pre-Distortion (DPD) is a strategy to expand linearity for non-linearity in power amplifiers. DPD executions can be grouped into memoryless models and models with memory. DPD is perhaps the most financially savvy linearization method. It includes a brilliant linearization capability, the capacity to safeguard overall efficiency, and it takes full advantage of advances in digital signal processors and A/D converters.
