1. A receiver for use in a modulated communications system wherein data is communicated in a time-slotted format and is subject to channel effects and co-channel interference, the receiver comprising:

  • circuitry for providing samples of a group of data from the time-slotted format;

    circuitry for determining a first set of channel estimates in response to a first set of the samples, the first set of channel estimates relating to the channel effects;

    circuitry for determining a first set of interference estimates in response to the first set of the samples and the first set of channel estimates, the first set of interference estimates relating to the co-channel interference;

    circuitry for first predicting decisions for data in the group of data in response to the first set of channel estimates and the first set of interference estimates;

    circuitry for determining a second set of channel estimates in response to the predicted decisions and without a correlation to a training sequence, the second set of channel estimates relating to the channel effects;

    circuitry for determining a second set of interference estimates in response to the predicted decisions and the second set of channel estimates, the second set of interference estimates relating to the co-channel interference; and

    wherein the circuitry for predicting is further for second predicting decisions for data in the group of data in response to the second set of channel estimates and the second set of interference estimates.
