Abstract: Method for optimal estimation of a propagation channel based solely on pilot symbols. A base of natural vectors is formed using the correlation matrix of the channel observed solely at the positions of the pilot symbols. Channel representation is broken down in this base. The base vectors are extended to the data symbols, which allows optimal interpolation of channel estimation to the data symbols. Application to OFDM, TDMA and CDMA systems.
