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