1. A method for enabling a receiving node to distinguish information simultaneously received from a plurality of transmitting nodes on a shared communication channel of a wireless digital network, the method comprising:
providing a plurality of parameter channels on the network in addition to the shared communication channel;
requiring each transmitting node to transmit a parameter-estimating signal on an unshared said parameter channel;
detecting the parameter-estimating signals on the unshared parameter channels and estimating therefrom at least one unique signal parameter for each of the transmitting nodes; and
detecting and distinguishing the information simultaneously received from each of the transmitting nodes according to their respective said unique estimated signal parameters.
