Abstract:
Decoding a received Orthogonal Frequency Division Multiplex (OFDM) signal that occupies a first set of subcarriers in a radio frequency spectrum includes ascertaining an interference model that represents interference occurring in the first set of subcarriers caused by a transmitted OFDM signal that occupies a second set of subcarriers in the radio frequency spectrum. A set of scaled soft values is produced that represents information conveyed by the received OFDM signal over the first set of subcarriers, wherein each scaled soft value in the set of scaled soft values corresponds to a respective one of the subcarriers in the first set of subcarriers, and wherein a scaling amount applied to each of the scaled soft values is based on a corresponding level of interference in said respective one of the subcarriers as indicated by the interference model. A decoding process is performed that generates detected data from the scaled soft values.
