Abstract

This study examines the techniques of radio frequency modulation and compensation in the context of orthogonal frequency division multiplexing (OFDM). The document details the implementation of various methods designed to mitigate disturbances, including amplitude and phase noise. The RF power amplifier (RFPA) emerges as a vital component in the configuration of radio devices for wireless communication, as it greatly enhances transmitter efficiency. Notably, this power amplifier is one of the most energy-consuming parts; for example, the lifespan of a cell phone battery is heavily reliant on the PA's power efficiency. Additionally, there is a significant need to ensure the transmission of data at the maximum possible rate for the allocated channel bandwidth, thereby promoting high spectral efficiency.
