Abstract

In this paper, we propose a pilot assisted adaptive channel estimation technique for 16-QAM/OFDM modulation based wireless system. Here mainly 5 channel models are under consideration: AWGN, Rayleigh-2, Rayleigh-10, Rayleigh-40, TU50. We also suggest a simplified formula for this method by interpreting simulation results of this system through different channel models under consideration.
