Abstract
A method of coding data, wherein a coding signal is used for coding data symbols, the coding signal comprising an orthogonal component and an error component, wherein a transmission signal depending on the data symbols and the coding signal is obtained by the coding, wherein the transmission signal is preferably obtained according to the equation S ( f ) = ∑ n = 1 N d n ψ n ( f ) , wherein N is the number of data symbols to be coded. The method determines a correction function and applies the correction function to the transmission signal in order to obtain a corrected transmission signal.
