Abstract
A receiver may include a first filter configured to generate a first estimation of a symbol of a received signal and a second filter configured to generate a second estimation of the symbol of the received signal. The receiver may also include a decoder configured to decode the symbol using one of the first estimation and the second estimation and a decision circuit configured to select one of the first estimation and the second estimation to provide to the decoder for decoding of the symbol based on a comparison of the first estimation to an estimation threshold.
Claims20
A receiver, comprising:
- an equalizer;
- a decision circuit configured to identify an error probability of the equalizer with respect to a particular signal;
- and
- a selection circuit to select the equalizer in response to a determination that the error probability of the equalizer with respect to the particular signal is below a threshold error value, the equalizer configured to process the particular signal responsive to the determination that the error probability of the equalizer with respect to the particular signal is below the threshold error value.
A method to process a particular signal, the method comprising:
- identifying an error probability of an equalizer with respect to the particular signal;
- determining that the error probability of the equalizer with respect to the particular signal is below a threshold error value;
- and
- selecting the equalizer in response to a determination that the error probability of the equalizer with respect to the particular signal is below a threshold error value, the equalizer configured to process the particular signal responsive to the determination that the error probability of the equalizer with respect to the particular signal is below the threshold error value
A receiver, comprising:
- a first equalizer;
- a decision circuit configured to identify a first error value for the first equalizer with respect to a particular signal;
- and
- a selection circuit to select the equalizer in response to a determination that the first error value for the first equalizer with respect to the particular signal is below a threshold error value, the equalizer configured to process the particular signal responsive to the determination that the first error value for the first equalizer with respect to the particular signal is below the threshold error value.
