Abstract

We address the downlink of a cellular multi-carrier CDMA (MC-CDMA) system taking into account channel estimation. The system performance in presence of a synchronization mismatch between two interfering base stations (BS) is analyzed in the way that a mobile terminal receives the perfectly synchronized signal from the desired BS as well as the signal from one interfering BS with a synchronization offset. It is demonstrated through simulations that spreading and cell specific random subcarrier interleaving effectively decorrelates the interfering signal, independent of the synchronization offset. Furthermore, the robustness of the channel estimator to cellular interference is examined
