Why Mastering EVM Is Essential for Next-Generation Wireless Systems
The white paper emphasizes the importance of mastering Error Vector Magnitude (EVM) in next-generation wireless systems like Wi-Fi, LTE, 5G NR, and satellite systems. It covers topics such as how EVM is calculated, the impact of digital modulation schemes on throughput and accuracy, and common sources of EVM degradation in transmitter and receiver systems. With the increasing complexity of modulation schemes, accurate modulation is crucial as even small deviations can lead to errors. The paper explains how EVM is used as a primary metric to quantify modulation accuracy and how constellation diagrams can help diagnose modulation impairments in practical wireless systems.
