Title : | Channel estimation performance analysis for comb-type pilot-aided OFDM systems with residual timing offset |
Authors : | Jeongho Park, Jihyung Kim, Changeon Kang and Daesik Hong |
Conference : | IEEE Conference Vehicular Technology |
Abstract : | The authors present an analysis of the effect of timing offset on channel estimation for comb-type pilot-aided orthogonal frequency division multiplexing (OFDM) systems. Residual timing offset does not negatively affect the channel estimation of the pilot subcarrier, but does corrupt the channel information obtained via interpolation. This paper provides the mean square error (MSE) channel estimation performance when a linear interpolation technique is used in a comb-type pilot-aided OFDM system. Analysis shows that the performance degradation of the channel estimator, which is due to imperfect frame synchronization, is dependent on the frequency correlation of the channels and the amount of timing offset arising from imperfect frame synchronization. |
