Process for the final reduction of the residual error probability during data transmission.

摘要

Method for defined reduction of the residual error probability in the transmission of data between at least one transmitter (1) and at least one receiver (2) which are interconnected via a transmission path (3), applicable for the residual error probability R (p): (See formula) with m - number of bits received counterfeit, d - Hamming distance of an applied code, N - bit length of the transmitted data block, H (m) - frequency of m bit error which the code can not recognize, p - bit error rate during a data transmission and q - probability that a bit in a non-falsified, wherein the transmitter (1) has means for receipt encoding and sending data and the receiver (2) has means for reception, coding and comparison of data, having the following steps: - generating a first code having a Hamming distance primea, through a first coding rule from the data to be transmitted through the transmitter (1), - generation of a second code, which has a second Hamming distance, by means of a second coding rule from the data to be transmitted through the transmitter (1), - outputting the data to the receiver (2), - generation of a third code which has the first Hamming distance, by means of the first coding rule from the data received via the receiver (2 ), - generating a fourth code which has the second Hamming distance, by means of the second coding rule from the data received through the receiver (2), - emitting the first and second code to the receiver (2 ), - comparison of the first with the third code and the second code with the fourth through the receiver (2), evaluation of the result of the comparison of the first with the third code and the second with the fourth code via the receiver (2), wherein the transmitter (1) has, as means for encoding the data, at least one first (8) and a second shift register (9) linear feedback shift and receiver ( 2) has, as means for encoding the data, at least one third (10) and a fourth shift register (11) linear feedback shift, wherein the first (8) and the third shift register (9) recoupled linearly use at least the same coding rule and the second (10) and the fourth shift register (11) linear feedback shift used in each case the same coding rule, where the specification respective coding is performed through a corresponding linear recoupling of shift registers (8, 9, 10, 11) respective and wherein for determining the Hamming distance of the coding specifications and / or the generated code, the totality of all forms unknown errors possible for the respective transmission data from a number of linearly independent data blocks in which the number of linearly independent data blocks in each case corresponds to the number of useful data bits.
