1. In a telecommunication system for communicating communication signals between various locations over a selected carrier medium wherein the communication signal is compressed to facilitate its transmission over the selected carrier medium and the communication signal is reconstructed after reception, an improved ending method comprising:

  • transforming the communication signal into two separate components including;

    determining the approximate center frequency Ω

    of the communication signal,mixing the communication signal with a selected mixing function of Ω

    t to product an in-phase component, andmixing the communication signal with a selected mixing function of Ω

    t to produce a quadrature component; and

    quantizing the separated signal components thereby encoding the signal components into quantized signals to produce a compressed encoded signal for transmission over the selected carrier medium of the communication system.
