Abstract
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.
Claims26
A receiver comprising:
- a first filter configured to generate a first estimation of a symbol of a received signal;
- a second filter configured to generate a second estimation of the symbol of the received signal;
- 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 or the second estimation to direct to the decoder for decoding of the symbol based on a comparison of the first estimation to a threshold,
- wherein the second filter is configured to generate the second estimation in response to the first estimation not satisfying the threshold such that the second filter does not generate the second estimation when the first estimation satisfies the threshold, and in response to the second filter generating the second estimation, the decision circuit is configured to direct only the second estimation to the decoder for the symbol.

A method to filter a signal, the method comprising:
- generating, using a first filter, a first estimation of a symbol of a received signal;
- comparing the first estimation to a threshold;
- in response to the first estimation not satisfying the threshold:
- generating, using a second filter, a second estimation of the symbol;
- and
- decoding the symbol using the second estimation instead of using the first estimation when the first estimation satisfies the threshold;
- generating, using the first filter, a third estimation of a second symbol of the received signal;
- comparing the third estimation to the threshold;
- and
- in response to the third estimation satisfying the threshold, decoding the symbol using the third estimation.
