Abstract
High-capacity, high quality services should be guaranteed in mobile communication environment. Excellent channel coding and compensation techniques are required so as to improve data reliability on fading channels. In this paper, we propose a method using double pilots, estimates and compensates for the fading of information symbols. The proposed method using Log-MAP Turbo decoder through the iterative decoder, improves BER performance under the environment of the frequency selective fading channel. Compared to the existing methods, the suggested methods show functional improvement of approximately 3dB in case that the number of iteration decoding is 5 and BER is $10^{-4}$.
