ABSTRACT:
A method of demodulating a signal in a transmission system where the modulation includes several substantially orthogonal subcarriers, and the vector of the propagation channel H[n,k] is known or the received signal includes at least pilot symbols emitting reference data. The method includes at least one step of estimating the symbol a[n,k] emitted on the kthsubcarrier of the nthsymbol of the modulation using a recombination step weighting the various signals received after synchronization and demodulation x[n,k].
