Classification: H04L

Abstract:
A symbol timing device, comprising:an ADC mechanism configured to sample a received signal at a predetermined over-sampling rate; a detector connected to said ADC mechanism and configured to detect a symbol identified by at least one of said samples during predetermined symbol times; and a symbol timing mechanism connected to said ADC mechanism and said detector and configured to read said samples and adjust a timing of the detection performed by said detector based on previously read samples so that the detected samples are at a most likely maximum eye opening of said samples during said predetermined symbol times; wherein: said symbol timing mechanism comprises, a histogram device configured to, store a histogram of said samples over a predetermined number of said symbol times, and calculate a most likely max eye opening of said samples of a next symbol time based on said histogram, and an adjustment device configured to adjust said timing of the detection performed by said detector based on the calculated most likely max eye opening.
