A method for coded data transmission between a base station (10) and at least one transponder (20) within a wireless data transmission system (1), the method comprising the steps of: -providing a set of symbols (S1 . . . S2n) for encoding data (DD), wherein the set of symbols (S1 . . . S2n) is divided into at least two sub-sets (SS1, SS2), and wherein each symbol (S1 . . . S2n) of the complete set is assigned to one of said at least two sub-sets (SS1, SS2); -encoding said data (DD) using symbols (S1 . . . S2n) of said at least two sub-sets (SS1, SS2), wherein at least one encoded symbol (S1 . . . S2n) comprises several bits; -transmitting each encoded symbol (S1 . . . S2n) within a symbol duration (SD) of an encoded data signal (DS) between said base station (10) and at least one transponder (20), wherein the sub-set (SS1, SS2) assigned to each encoded symbol (S1 . . . S2n) is indicated by a value of at least one bit (LB) of each encoded symbol (S1 . . . S2n); -identifying the value of said at least one bit (LB) of the transmitted encoded symbols within the encoded data signal (DS); -determining the sub-set (SS1, SS2) assigned to each encoded symbol (S1 . . . S2n) depending on the identified value of said at least one bit (LB); and-decoding each encoded symbol (S1 . . . S2n) according to the determined sub-set (SS1, SS2).
