An over-sampled sequence detector operates on sampled data and tracks the detection reliability of the sampled data. The detector separately analyzes sample sequences for different sampling phases and then picks a sample sequence that allows for the most reliable detection. For the different sampling phases, the detector inspects some amount of look-behind and look-ahead information in order to improve upon simple symbol-by-symbol detection. The over-sampled information is used to further improve detection performance. In one embodiment, a method for receiving data over a digital transmission link comprises: receiving a sequence of samples generated to represent a sequence of symbols, the sequence of samples comprising a first and second sample stream according to a first and second phase of the sequence of samples; detecting a first and second symbol from the first and second sample streams; and estimating a first and second detection reliability of the first and second symbols.
