Abstract:
1. A method for operating a piconet operable device that operates within a first piconet, the method comprising: receiving a signal that includes a first symbol that has collided with a second symbol transmitted within a second piconet; estimating interference associated with the collision within the first symbol on a power per bit basis; detecting an energy of the first symbol; comparing the energy of the first symbol to a predetermined energy or to an estimated energy; determining whether a difference between the energy of the first symbol and the predetermined energy exceeds at least one threshold from among a plurality of thresholds or whether a difference between the energy of the first symbol and the estimated energy exceeds at least one threshold from among the plurality of thresholds; when the difference exceeds a first threshold of the plurality of thresholds and no other threshold of the plurality of thresholds, selectively de-weighting the first symbol according to a first de-weighting factor and providing the de-weighted first symbol to a decoder; when the difference exceeds the first threshold and a second threshold of the plurality of thresholds and no other threshold of the plurality of thresholds, selectively de-weighting the first symbol according to a second de-weighting factor and providing the de-weighted first symbol to the decoder; and when the difference does not exceed any threshold of the plurality of thresholds, providing the first symbol to the decoder.
