A method for a terminal of a cellular telecommunication system, the telecommunication system enabling determination of the system information by the terminal from system information from at least one cell operated by a network node of the telecommunication system, where the telecommunication system employs Orthogonal Frequency Division Multiple Access. The method comprises receiving a transmission signal, comprising reference symbols and synchronisation symbols, from the network node of the at least one cell; determining at least one pre-coding vector, of which one pre-coding vector being associated with transmission by an at least one transmit antenna of the network node of the at least one cell, for the transmission signal; and estimating, for each of the at least one pre-coding vector, a channel estimate for all sub-carriers of the received transmission signal from the received reference symbols and a reference symbol channel model defined for reference symbols of the transmission signal, and from the synchronisation symbols, the at least one pre-coding vector and a synchronisation symbol channel model defined for synchronisation symbols of the transmission signal. Decoder, terminal, and computer program with corresponding features are also disclosed. |
