Abstract :
In this paper, a new subspace-based adaptive semi-blind channel estimation method is proposed for zero padding OFDM systems. The algorithm is fully adaptive in the sense that both the subspace information and the optimization .Not only does this algorithm reduce computation complexity, but improves the convergence rate in channel estimation. Simulations demonstrate the effectiveness of the proposed algorithms.
