Abstract

Die Erfindung betrifft ein Verfahren zum Übertragen von digitalen Informationen zwischen einem Sender (S) und einem Empfänger (E), wobei senderseitig ein serieller Strom (ST) von Informationsbits in eine Mehrzahl von parallelen Strömen (PS1, PS2, PS3) aufgeteilt wird. Die Informationsbits der parallelen Ströme (PS1, PS2, PS3) werden durch Kodierung in kodierte Bits (KB1, KB2, KB3) umgewandelt. Die kodierten Bits (KB1, KB2, KB3) werden in Form von Symbolen (SYM) an den Empfänger (E) gesendet, wobei in die Symbole (SYM) jeweils ein kodiertes Bit (KB1, KB2, KB3) eines jeden parallelen Stromes (PS1, PS2, PS3) eingeht. Die kodierten Bits (KB1, KB2, KB3) werden in Form von Symbolen (SYM) an den Empfänger (E) gesendet. Erfindungsgemäß werden aufgrund mindestens einer Fehlermeldung (NAK) von dem Empfänger (E), betreffend empfangene kodierte Bits einer Teilmenge von parallelen Strömen der Mehrzahl der parallelen Ströme (PS1, PS2, PS3), zuvor bereits gesendete kodierte Bits (KB1, KB2, KB3) der in der mindestens einen Fehlermeldung (NAK) indizierten kodierten Bits und/oder zuvor nicht gesendete kodierte Bits, basierend auf Infnormationsbis der Teilmenge von parallelen Strömen, auf welchen die in der mindestens einen Fehlermeldung (NAK) indizierten kodierten Bits basieren, an den Empfänger (E) gesendet. Weiterhin betrifft die Erfindung einen Sender und einen Empfänger zur Durchführung des Verfahrens.The invention relates to a method for transmitting digital information between a transmitter (S) and a receiver (E), wherein the transmitter side, a serial stream (ST) of information bits in a plurality of parallel streams (PS1, PS2, PS3) is divided. The information bits of the parallel streams (PS1, PS2, PS3) are converted by encoding into coded bits (KB1, KB2, KB3). The coded bits (KB1, KB2, KB3) are sent in the form of symbols (SYM) to the receiver (E), wherein in the symbols (SYM) in each case one coded bit (KB1, KB2, KB3) of each parallel stream (PS1 , PS2, PS3). The coded bits (KB1, KB2, KB3) are sent in the form of symbols (SYM) to the receiver (E). According to the invention, based on at least one error message (NAK) from the receiver (E), regarding received coded bits of a subset of parallel streams of the plurality of parallel streams (PS1, PS2, PS3), previously encoded bits (KB1, KB2, KB3) already transmitted. the coded bits indexed in the at least one error message (NAK) and / or coded bits not previously transmitted, based on infnormation to the subset of parallel streams on which the coded bits indexed in the at least one error message (NAK) are based, to the receiver ( E). Furthermore, the invention relates to a transmitter and a receiver for carrying out the method.
