Abstract: The invention relates to a receiver which forms part of a communication system and receives data frames through a communication channel which is subject to disturbances, said receiver carrying out an estimation of the maximum error rate and minimum error rate caused by the communication channel. The receiver in a first time period verifies the validity of the received data frames so as to detect and identify the received erroneous data frames and the received correct data frames. Subsequently, the receiver proceeds to correct those received erroneous data frames which can be corrected, so as to generate corrected data frames. The erroneous bits are detected through a bit-by-bit comparison of the erroneous data frames 302 and the corresponding corrected data frames 303, which are added together and then averaged over the total number of bits nb_total_bits received by the receiver so as to obtain a minimum error rate for the transmission.

Abstract: The invention relates to a method of protecting against transmission errors for frames of digital primary data comprising primary data of different priorities, so as to supply via a communication channel data frames which are protected against the transmission errors. A priority level associated with the primary data is determined, on the one hand for informing the protection step carrying out the protection against the errors thereof and on the other hand for taking a decision on the necessity of protecting said primary data. The protection step against the errors, of the FEC type, renders it possible to deliver the protected data on the basis of said primary data through the addition of a quantity of redundancy information to each type of primary data, which quantity depends both on their priority level and on a value indicative of the quality of the communication channel.
