SAMPLE VALIDITY DETERMINATION METHOD AND APPARATUS FOR DIGITAL PREDISTORTION APPARATUS

摘要

A sample validity determination method and apparatus for a digital predistortion apparatus are disclosed. The main purpose of the present embodiment is to provide a sample validity determination method and apparatus for a digital predistortion apparatus, which is for compensating for the non-linearity of a power amplifier and can efficiently compensate for the non-linearity of a power amplifier by accurately estimating a predistortion coefficient even with a low-capacity memory.
