DOI: 10.1109/tcomm.2017.2748127
Abstract: In this paper, we derive the data-aided error vector magnitude (EVM) in an interference limited system when both the desired channel and interferers experience independent and nonidentically distributed $\kappa - \mu $ shadowed fading. Then,… read more here.

DOI: 10.1109/tim.2022.3145351
Abstract: Error vector magnitude (EVM) is one of the key parameters to quantify the performance of a digital radio transmitter or receiver. However, the measurement method of EVM has not been formed properly, especially for those… read more here.
