Abstract

The digital modulation signal is usually encountered in five kinds of distortion factors

including I/Q gain imbalance

phase offset

continuous wave interference

phase noise and additive Gaussian noise.Through mathematical derivation

a complete mathematical formula is obtained

to calculate EVM by five distortion factors.At the same time

two experiments are carried out

in conjunction with numerical simulation to verify the formula.Formula and measurement results fit well.
