| 摘要 |
<p>The invention relates to a data transmission system and method for encoding a signal to be transmitted in a data transmission system, the method allowing data to be transmitted at various different transmission rates, data being transmitted in the method in frame format, the frames (100) also comprising information about the used transmission rate, conveyed by means of control bits (106), the control bits being encoded by using a biorthogonal coding to provide encoded bits. To allow the transmission rate used in a frame to be flexibly indicated, the used biorthogonal coding depends on the number of the different transmission rates and the encoding is selected so that the number of encoded bits remains constant. <IMAGE></p> |
