1. A method of coding an information signal comprising:

  • representing the information signal by a sequence of pulses;

    determining a plurality of pulse parameters based on the sequence of pulses including a non-zero pulse parameter corresponding to a number of non-zero pulse positions in the sequence of pulses;

    coding the non-zero pulse parameter using a variable-length instantaneously decodable codeword; and

    coding at least one of a remaining plurality of pulse parameters to produce a codeword having a corrsponding length based on the number of non-zero pulse positions.
