Patent ID: 7499506

Claim:
A computer program product comprising a computer readable medium having instructions stored thereon when executed to estimate a modulation format of a signal being modulated, the signal comprising a plurality of blocks, each block comprising a plurality of bursts, the computer program product comprising sets of instructions for: a) determining a first modulation format estimation of a first burst of a block; and b) determining a second modulation format estimation of a second burst of the block using information relating to the first modulation format estimation; said determinings comprises: determining a first delta signal-to-noise ratio (SNR) comprising the difference in SNRs of the first burst modulated in the first modulation format and the first burst modulated in the second format; determining a second delta SNR comprising the difference in SNRs of the second burst modulated in the first modulation format and the second burst modulated in the second modulation format; determining that the difference in the first and second delta SNRs is greater than a predetermined confidence metric; determining that the second modulation format estimation is not equal to the first modulation format estimation; and resetting the second modulation format estimation to equal the first modulation format estimation.
