摘要：
In this paper, the effect of phase noises (PNs) of multiple users on orthogonal frequency division multiplexing (OFDM) based multiple-input multiple-output (MIMO) systems is studied. It is assumed that each of the users has a single antenna, whereas the base station (BS) has multiple antennas and use zero-forcing (ZF) decoder for multi-user detection. Since each user is equipped with an independent oscillator, the received uplink (UL) signal at each BS antenna is corrupted by all of these independent PNs. Analytical study on the performances of the MIMO-OFDM system in the presence of multiple PNs is presented and the analytical results are verified by simulations.
