Modelling to study its non-linear effects on Communication System's performance with BER as performance measure

TL;DR

This paper investigates how non-linear effects of RF amplifiers, especially gain compression, impact the performance of multilevel modulation schemes like MPSK and MQAM in communication systems, using BER vs SNR curves.

Contribution

It presents a detailed analysis of non-linear RF amplifier effects on multilevel modulation schemes and their impact on system performance measured by BER.

Findings

Non-linear effects cause significant BER degradation at high SNRs.

Gain compression notably affects MPSK and MQAM performance.

BER vs SNR curves illustrate the impact of non-linearity on communication reliability.

Abstract

This paper is a study of non-linear effects of RF Amplifiers on Communication Systems Performance. High speed data communication is made possible by Multilevel Modulation schemes. This paper presents a study of these non linear effects on multilevel Modulation schemes like MPSK and MQAM. We make use of Bit Error Ratio (BER) as performance measure. BER vs SNR (Signal-to-Noise Ratio) curves provide comparison between the non linear effects caused by Gain Compression in particular.
