DIGITAL PRE-DISTORTION AND ASSISTANCE INFORMATION SIGNALING: abstract simplified (17655517)

The abstract describes a technique called digital pre-distortion (DPD) for improving wireless communication. The technique involves using two DPD circuits and a power amplifier (PA) in an apparatus. The first DPD circuit takes an input signal, applies a first DPD to it, and generates a first resulting signal. This first resulting signal is then passed to the second DPD circuit, which applies a second DPD to it and generates a second resulting signal. The second resulting signal is amplified by the PA to create an amplified second resulting signal, which is then transmitted to another device.
