| titleOfInvention | Correction-calculation algorithm for estimation of the signal to noise ratio in high bit rate DMT modulation |
| abstract | A method for correcting signals received on a channel. Signals are received along the channel and it is determined how many of the signals are outside a predetermined range relative to a plurality of predetermined constellation points (i.e., erasures). Then, the noise power is estimated the noise power based on the number erasures, and the noise power is used to correct the signals. Specifically, the estimated noise power can be used to correct the signals which have been determined to be outside the predetermined range and which have been determined to contain a large error component (i.e., based on distance from the closest constellation point). A look up table can be used to determine the correction to be applied, and a separate look up table can be used for each tone. |
