| Abstract | The aim of this paper is to share novel paradigm of channel estimation for orthogonal frequency division multiplexing (OFDM) systems. OFDM is used to improve spectral efficiency and spatial diversity in wireless communications systems. This paper provides a review of channel estimation techniques (blind and pilot-aided) and its performance on data-aided channel. After comparison with known techniques the blind channel estimation perform better as compare to pilot aided system. In addition pilot cost overhead in wireless communications system. By evaluate pseudo-pilot concept, overhead cost overcome which offer identical performances as conventional pilot system.
