Abstract

Based on the orthogonality between the used and the unused spreading codes (excess codes) subspaces in one hand and on the restoration of guard interval redundancy of Multicarrier Code Division Multiple Access signal in other hand, we propose joint Carrier Frequency Offset and time domain equalizer estimators. A major difficulty arises from the highly complexity of these methods. Use of an approximation method or an adaptive algorithm has been popular approach to ease problem solving. Our derived methods are found to be good in terms of estimation accuracies, computation complexity, and convergence speed when compared to the block processing algorithms.
