Summary :

In this paper the conventional symbol-aided estimation methods are extended to use not only the known pilot symbols but also the previously estimated fading values to extract more information on fading channels. The proposed estimation method is evaluated using theoretical analyses. Recursive formulae are derived for calculating the mean square estimation errors, which are then used to calculate the BER performance of a BPSK system employing the proposed fading estimation method. The results show strong BER performance of the proposed system in the region of high signal to noise ratio under fast fading compared to that of the conventional system. Moreover, the proposed system still sustains its performance under mismatched conditions, where the conventional system degrades exhibiting error floors. Finally the theoretical results are verified by using computer simulations.
