Channel estimation techniques for CDMA systems need to combat multiple access interference and near-far effects to improve the estimation performance. Linear single-user MMSE detector has certain advantages with respect to near-far problem. In this paper, single-user MMSE detector is used to develop an iterative near-far resistant radio channel estimation algorithm. Computer simulation results demonstrate that a significant performance improvement against conventional single-user estimator can be achieved with the developed method especially under extreme near-far conditions.
