Abstract

A new technique for tracking of fast fading channels in long code CDMA is proposed. Using a linear interpolation model, the proposed method tracks the time-varying channel without pilot symbols or with sparsely inserted pilots. The proposed method can be implemented efficiently using a state space inversion technique. A new identifiability condition is established and the performance of the method is assessed through the mean square error and bit error rate.
