1. A method of transmitting two signals on a single channel comprising a single frequency and a single time slot, the method comprising:

  • generating a first training sequence from a first set of training sequences, wherein a training sequence is a known sequence transmitted in a signal in a time slot burst;

    generating a second training sequence from a second set of training sequences, the second training sequence being different from the first training sequence, the first and second training sequences having a low cross-correlation ratio with respect to each other; and

    the second set of training sequences being different from the first set of training sequences;

    generating first data;

    generating second data;

    combining the first data with the first training sequence to produce first combined data;

    combining the second data with the second training sequence to produce second combined data; and

    transmitting on the single channel by a single transmitting apparatus a first signal comprising the first combined data and a second signal comprising the second combined data, wherein the single transmitting apparatus is part of a base station;

    the first and second signals are for respective first and second remote stations; and

    the single base station serves the first and second remote stations.
