A system and method for recovering the seed of a pseudo-random binary sequence (PRBS) using soft decisions is disclosed. In some implementations, a log-likelihood ratio is calculated to determine the certainty with which each bit in the seed has been recovered, and in some implementations, the value of the PRBS is used in the calculation of the log-likelihood ratio. In some implementations, a linear feedback shift register stores the log-likelihood ratio for each bit in the sequence. |
