A transmission system comprising a transmitter with a signal encoder, the signal encoder having an input for a signal to be encoded and a codebook entry selector for selecting a codebook entry for obtaining a synthetic signal giving a best approximation of a signal representative of the input signal, wherein the codebook entry includes a plurality of samples that can assume more than two values and is identified with a sequence of symbols, a receiver having a decoder with a codebook for deriving the codebook entry from the sequence of symbols received from the transmitter, wherein the codebook entries corresponding to sequences of symbols that differ in one particular symbol value also differ in one single sample value.
