Abstract
A receiver including an equalization component to receive a signal comprising a sequence of samples corresponding to symbols and generate an equalized signal with an estimated sequence of symbols corresponding to the signal. The receiver further includes a decision generation component to receive the equalized signal and generate, based on the equalized signal, a decision comprising a sequence of one or more bits that represent each symbol of the sequence of symbols and a confidence level corresponding to the decision.
Claims19
A digital receiver comprising:
- an equalization component to:
- receive a signal comprising a sequence of samples corresponding to symbols;
- and
- generate an equalized signal with an estimated sequence of symbols corresponding to the signal;
- and
- a decision generation component to:
- receive the equalized signal;
- identify a first set of symbols of at least a portion of one or more blocks of the equalized signal;
- generate a first vector of a first sequence of the first set of symbols;
- and
- generate a second vector of a second sequence of the first set of symbols;
- and
- generate, based at least in part on the first vector and the second vector, a decision comprising a sequence of one or more bits that represent each symbol of the sequence of symbols and a confidence level corresponding to the decision.

- and
- a generator module to generate, based on the set of symbol probabilities, a decision comprising a sequence of one or more bits that represent each symbol of the sequence of symbols and a confidence level corresponding to the decision.
