Abstract
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.
Claims24
A method for receiving data over a digital transmission link, comprising:
- 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.
An apparatus for receiving data over a digital transmission link, comprising:
- a receiver for:
- (a) 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;
- (b) detecting a first and second symbol from the first and second sample streams;
- and
- (c) estimating a first and second detection reliability of the first and second symbols.
A computer-readable medium having computer-executable instructions recorded thereon for enabling a processor of a computer system to process incoming data over a digital transmission link the computer-executable instructions comprising:
- 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.
