1. A method of enhanced message detection in a wireless network, the method comprising:

  • receiving a plurality of input signals on a plurality of input channels;

    dividing the input signals into a first input group and a second input group, wherein each of the input groups includes at least one of the input signals, and each of the input signals is included in only one of the input groups;

    for each of the input signals in both of the input groups, correlating the input signal with a corresponding expected input and deriving therefrom an unmitigated correlation;

    combining the unmitigated correlations from the first and second input groups to obtain an unmitigated correlation score;

    for each input signal in the first input group, applying interference mitigation thereto to derive a mitigated input signal, correlating the mitigated input signal with the corresponding expected input, and deriving therefrom a mitigated correlation;

    combining the mitigated correlations to obtain a mitigated correlation score;

    combining the mitigated correlations with the unmitigated correlations from the second input group to obtain a mixed correlation score;

    comparing the unmitigated, mitigated, and mixed correlation scores with corresponding predetermined detection thresholds; and

    detecting a message if at least one of the correlation scores is above its corresponding detection threshold.
