摘要:
A method and system for a cellular telecommunication system is provided. A transmission signal, which includes reference symbols and synchronization symbols, is received from the network node of at least one cell. At least one pre-coding vector is determined for the transmission signal, where one pre-coding vector is associated with transmission by at least one transmit antenna of the network node of the at least one cell. For each of the at least one pre-coding vectors, a channel estimate is estimated 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 synchronization symbols, the at least one pre-coding vector, and a synchronization symbol channel model defined for synchronization symbols of the transmission signal.
