On channel estimation in OFDM systems

van de Beek, Jan-Jaap; Edfors, Ove LU ; Sandell, Magnus; Wilson, Sarah Kate and Börjesson, Per Ola LU (1995) IEEE Vehicular Technology Conference, 1995 In Proc. IEEE Vehicular Technology Conference 2. p.815-819
Abstract
The use of multi-amplitude signaling schemes in wireless OFDM systems requires the tracking of the fading radio channel. The paper addresses channel estimation based on time-domain channel statistics. Using a general model for a slowly fading channel, the authors present the MMSE and LS estimators and a method for modifications compromising between complexity and performance. The symbol error rate for a 18-QAM system is presented by means of simulation results. Depending upon estimator complexity, up to 4 dB in SNR can be gained over the LS estimator
