摘要：
This work explores the possibility to adapt the pilot location in an OFDM frame, by choosing the more appropriate pilot pattern, the rectangular or the hexagonal one. Based on the prediction of some channel parameters and for a given pilot density, the transmitter seeks the most appropriate time-frequency pilot spacing which minimize the MSE of the channel estimated by the use of a general interpolator.
