A method for transmitting a digital signal is provided comprising generating a representation of the digital signal in the frequency domain, wherein the representation comprises, for each of a plurality of sub-spectrums of the spectrum of the digital signal, at least one frequency coefficient; generating, for each sub-spectrum, a bit-stream from the at least one frequency coefficient of the sub-spectrum; determining, for each bit-stream, a truncation point; truncating each bit-stream according to the truncation point determined for the bit-stream and transmitting data according to the truncated bit-streams.
