Methods and systems for detecting symbol erasures
First Claim
1. A method for determining a symbol erasure threshold for a received signal containing symbol information, comprising:
- performing a first threshold calculation to produce an initial symbol erasure base-threshold;
performing a first margin calculation to produce an initial symbol erasure margin; and
modifying the initial symbol erasure base-threshold using the initial symbol erasure margin to produce a modified symbol erasure threshold.

Abstract
A technique for determining a symbol erasure threshold for a received communication signal containing symbol information is disclosed. The technique begins by performing a first threshold calculation to produce an initial symbol erasure threshold, then performing a first margin calculation to produce an initial symbol erasure margin and then modifying the initial symbol erasure threshold using the initial symbol erasure margin to produce a modified symbol erasure threshold. By then periodically modifying the modified symbol erasure threshold adaptive via updating the symbol erasure threshold and/or symbol erasure margin based on various error quantities, the technique can compensate for time-variant considerations, such as drifting noise levels.
