N2 - In this paper, the performance of multicarrier (MC) code-division multiple access (CDMA) systems in the presence of carrier frequency offset (CFO) with beamforming techniques is evaluated. A conventional uniform linear array (ULA) beamformer is utilized. An independent Nakagami fading channel is assumed for each subcarrier of all users. The performance of outage probability is investigated under a scenario where perfect beamforming is assumed. A closed-form expression of the outage probability performance is derived. Numerical results show that the performance of outage probability improves significantly as the number of antenna elements increases. The effect of CFO on the outage probability is reduced significantly when the beamforming technique is employed.
