Abstract :
This paper presents the performance of turbo codes in fading multipath channels. We apply two channel estimation techniques, namely, the pilot tone technique and the pilot symbol assisted modulation technique to obtain channel side information for decoding. Various channel models are used in computer simulations. Numerical results are given to quantify various system behavior and to provide numerical examples that provide us system solutions
