Abstract
The invention relates, according to the first form thereof, to a transmission error correction method, wherein at least two encoded binary series from a binary series that is to be transmitted and encoded by means of a convolutional code are received from a communication channel. Said method is characterized in that same comprises the following steps: producing, from two received encoded binary series, comparison binary series that coincide in the absence of transmission errors on the communication channel; comparing the comparison binary series and forming a detection binary series corresponding to the logic operation OU-exclusive of the two comparison binary series; and, in the event that the comparison binary series diverge from a divergence point, verifying if the series made up of P bits of the detection binary series from the divergence point corresponds to a listed transmission error and correcting, if necessary, the received encoded binary series.
