Abstract

In this paper, a semi-blind channel estimator using receiver diversity is proposed for OFDM systems in the presence of virtual carriers over a time-dispersive channel. We insert a pilot to each data block to resolve the inherent scalar ambiguity of blind identification. The computation complexity of this algorithm is also studied and reduced. By simulation, this algorithm supplies accurate estimation with small expense.
