Abstract:
A method for decoding a received value, comprising:determining whether said received value is in a space containing first and second possible decode values, said space having a boundary substantially equidistant from said first and second possible decode values and separating said first and second possible decode values, wherein if said received value is within a first portion of said space closest to a point associated with first decode value, said received value is decoded as said first decode value, and if said received value is within a second portion of said space closest to a point associated with second decode value, it is decoded as said second decode value; producing a value that estimates an amount of jitter noise in a channel through which said received value has passed; and moving said boundary an additive amount determined by said value that estimates an amount of jitter noise, wherein said boundary is moved to enlarge whichever of said first and second spaces that contains a larger amount of jitter noise.
