Claim One:
1. A method of generating an interference hypothesis indicating the presence of a predetermined level of interference in a communication signal having at least one channel estimation symbol, the method comprising: a) estimating a true noise variance using along-term data aided algorithm; b) estimating an interference variance using a short-term data aided algorithm; and c) determining an interference hypothesis based on comparing the true noise variance estimate and the interference variance estimate by: i) of the at least one channel estimation symbol; ii) verifying that the computed received signal power for a channel estimation symbol is within a predetermined threshold of another computed received signal power for another channel estimation symbol; iii) comparing the true noise variance estimate to the interference variance estimate; and iv) setting an interference hypothesis to indicate that interference is present if the computed received signal power for the channel estimation symbol is within the predetermined threshold and the true noise variance estimate is within a predetermined threshold of the interference variance estimate.
