Abstract
A transmission system for transmitting data over a channel in the form of a digital signal comprising bits of data, the system comprising an encoder for encoding the data prior to transmission, the encoder producing coding in the form of an overhead, and a decoder for decoding the data after transmission, characterised in that a first portion only of the data is encoded, the second portion remaining uncoded, the system further comprising a partitioner for partitioning the overhead from the uncoded data portion of the signal, after the first portion data has been encoded.
