Error Vector Magnitude Analysis in Generalized Fading With Co-Channel Interference

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 <inline-formula> <tex-math notation="LaTeX">$\kappa - \mu $ </tex-math></inline-formula> shadowed fading. Then, it is analytically shown that the EVM is equal to the square root of number of interferers when the desired channel and interferers do not experience fading. Furthermore, the EVM is derived in the presence of interference and noise, when the desired channel experiences <inline-formula> <tex-math notation="LaTeX">$\kappa - \mu $ </tex-math></inline-formula> shadowed fading and the interferers experience independent and identical Nakagami fading. Moreover, using the properties of the special functions, the derived EVM expressions are also simplified for various special cases.
