Abstract (en)
[origin: WO0223841A1] The invention concerns a method for optimal estimation of a propagation channel relying solely on pilot symbols. It consists in: constituting a base of eigenvectors from the correlation matrix of the observed channel only at the locations of the pilot symbols; breaking down the representation of the channel in said base; extending the base vectors to the given symbols, thereby producing an optimal estimation of the channel to the data symbols. The invention is applicable to OFDM, TDMA, CDMA systems.
