Channel estimation using pilot is common used in OFDM *** pilot is usually time division multiplexed with the informative *** of the main drawbacks is bandwidth *** this paper,a new method was proposed to perform channel estimation in OFDM *** pilot is arithmetically added to the output of OFDM *** uses the hidden pilot to get an accurate estimation of the *** pilot is removed after channel *** Cramer-Rao lower bound for this method was *** performance of the algorithm is then *** with traditional methods,the proposed algorithm increases the bandwidth efficiency dramatically.
