Channel estimate predicted from several previous channel estimates, for pre-equalization

摘要

A data transmission method includes transmitting an encoded data signal in form of a data stream of data bursts between a transmitter and a receiver, making a decision as a function of at least one data transmission parameter as to whether an interference treatment of the data signal to be transmitted will be performed in the transmitter or in the receiver, performing the interference treatment in terms of at least on code in the transmitter, and performing the interference treatment of the data to be transmitted in terms of at least one further code in the receiver.
