System and method implementing soft-decision based excision cancellation technology

A system, comprising:

• a processor;
• a non-transitory computer-readable storage medium comprising programming instructions that are configured to cause the processor to implement a method for mitigating an effect of interference, wherein the programming instructions comprise instructions to:
• receive a signal comprising at least one interfering signal component;
• generate 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 a 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
• use the soft values to cancel the at least one interfering signal component from the signal to mitigate the effect of interference.
