Abstract:	This paper deals with data-aided channel estimation in systems using OFDM modulation. We formulate a pilot symbol-based channel estimator and compare it with the pilot-tone one proposed in [1]. Although this paper focuses in flat fading mobile channels, the results could easily be applied to OFDM systems operating in frequency-selective channels.
