摘要

The Error Vector Magnitude (EVM) is a useful magnitude in the development and design process to indicate the entire signal quality. The post-equalized signal has better performance than pre-equalized signal due to its robustness against noise during channel equalization processing under ideal and interpolation channel estimation. The EVM performance decrease as the SNR decreases according to the simulation results.
