In order to maximize the spectral efficiency, the current wireless systems tend to allocate the same frequency resources to different users, which causes the so-called Co-Channel Interference (CCI) on the signal received by the mobile user. If not handled appropriately, CCI may seriously degrade the communication performance. Therefore, for more reliable performance, robust transceiver techniques are required. In this paper, the authors consider WiMAX systems as example and propose a CCI cancellation method at the mobile user side based on a realistic cell-edge scenario.
