ABSTRACT:
A technique is provided to generate a sequence of symbols to be transmitted, comprising transmitting a block of symbols having data and redundancy symbols, the redundancy symbols generated based on the data symbols, a first part of the redundancy symbols transmitted as a prefix of the block, a second part of the redundancy symbols transmitted as a postfix of the block and a third part of the redundancy symbols transmitted as an intermediate part of the block between the prefix part and postfix part. The first part may be generated from the symbols transmitted at the end of a data portion of the block, the second part may be generated from the symbols transmitted at the start of the data portion of the block, the third part may be generated from an entire sequence of non-redundant data symbols transmitted in the first half of the data portion of the block.
