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 to process the input signal and generate resulting signals. The first DPD circuit applies a first distortion correction to the input signal and passes it to the second DPD circuit. The second DPD circuit applies a second distortion correction to the first resulting signal and passes it to a power amplifier (PA). The PA amplifies the second resulting signal, which is then transmitted to another device.
