Method for determining a copy to be decoded and an associated erasures vector, corresponding storage means and receiver device

摘要

A method is proposed for determining an erasures vector associated with a data block to be decoded built out of received copies, and using levels of reliability of transmission associated with symbols contained in different copies of a same block of received pieces of data. Such a method advantageously makes reduces the error rate at output of a decoder by minimizing the operations to be performed to determine the erasures vector, marking the erasures and preventing the generation of an excessively large number of erasures (even when the transmission of certain received copies is unreliable) to have a number of erasures that does not exceed the correction capacity of the decoder.
