Error Vector Magnitude Analysis of Uplink Multiuser OFDMA and SC-FDMA Systems in the Presence of Nonlinear Distortion

We analyze the impact of nonlinear distortion on the performance of uplink multiuser orthogonal frequency division multiple access and single carrier-frequency division multiple access systems in terms of the error vector magnitude (EVM). Based on the power spectrum density of the distortion noise, we derive a unified framework of theoretical EVM for both systems. The obtained results provide us approaches to evaluation of both the self-distortion and the inter-distortion interference from other users. In addition, simulation results agree well with our theoretical analyses.
