Abstract
The invention provides a multicarrier system constructed on a time-frequency lattice defined comprising frames having MxN symbols distributed over M subcarriers each of which is divided into N specific symbol times. Each frame comprises P pilot symbols distributed time-wise and frequency-wise so as to cover the frame in a meshed structure, so that, in particular, some at least of the M subcarriers contain no pilot symbol and/or that no pilot symbol should be transmitted to some at least of the N symbol times. The invention also relates to a method for tracking a transmission channel using such a signal, and a device for implementing the method.
