1. A bandwidth efficient modem in a multi-user environment for determining whether additional users can be added to a system, comprising:

  • a front end unit for processing input received signals into a baseband waveform;

    a baseband waveform processor performing parameter estimation and demodulation of said baseband waveform;

    a digital signal processor for reconstructing an estimate of each said interfering signal and calculating a noise power, wherein said noise power is used to determine whether there is a sufficient noise margin to add said additional users, and wherein said reconstructing requires data from said parameter estimation and demodulation; and

    a waveform generator for processing channel communications, wherein said channel communications consist of message and signal information, communicated to said system.
