Abstract:
1. A data-recovery apparatus, comprising: a first generator configured to calculate a first value and a second generator configured to calculate a second value, the first and second values being related to a level of interference at a carrier frequency of a multi-carrier signal received over a channel; a first comparator configured to compare a third value to a fourth value and a second comparator configured to compare a fifth value to a sixth value, the third value being related to the first value, the fourth and sixth values being related to a response of the channel at the carrier frequency, and the fifth value being related to the second value; and first and second detectors each configured to recover a data value transmitted at the carrier frequency from a data value received at the carrier frequency, the first detector configured to recover the transmitted data value according to a first algorithm if the third value has a first mathematical relationship to the fourth value, and the second detector configured to recover the transmitted data value according to a second algorithm if the third value does not have the first mathematical relationship to the fourth value and the fifth value has a second mathematical relationship to the sixth value.
