1. A method for mitigating an effect of interference, comprising:
receiving, by a device, a signal comprising at least one interfering signal component;
generating, by the device, a soft value for each symbol in the at least one interfering signal component, the soft value representing a most likely value for the symbol which is obtained by
determining a probability metric between an actual value of the symbol and each of a plurality of possible symbol values using a scaling value representing an estimate of a noise level in the signal received by the device,
generating current local probabilities for the plurality of possible symbol values using the probability metric, and
using the current local probabilities to determine the soft value; and
using, by the device, the soft values to cancel the at least one interfering signal component from the signal to mitigate the effect of interference.
