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:
- a first filter operable to generate a first estimation of a symbol in a received signal;
- a second filter operable to generate a second estimation of the symbol in the received signal;
- and
- a decision circuit to enable the first filter and disable the second filter causing the first filter to generate the first estimation and the first estimation to be directed to a decoder to decode the symbol based on a comparison of the first estimation to a threshold,
- wherein in response to the first estimation failing to satisfy the threshold, the decision circuit is configured to disable the first filter and enable the second filter causing the second estimation to be directed to the decoder to decode the symbol based on a comparison of the second estimation to the threshold.
A method, comprising:
- enabling, by a decision circuit, a first filter;
- generating, using the first filter, a first estimation of a symbol of a received signal;
- comparing the first estimation to a threshold;
- and
- in response to the first estimation not satisfying the threshold:
- disabling, by the decision circuit, the first filter;
- enabling, by the decision circuit, a second filter;
- generating, using the second filter, a second estimation of the symbol;
- and
- decoding the symbol using the second estimation instead of using the first estimation.
A non-transitory computer-readable medium configured to store instructions, the instructions configured to be executed by a processor to configure a system to perform operations, the operations including:
- enable, by a decision circuit, a first filter;
- generate, using the first filter, a first estimation of a symbol of a received signal;
- compare the first estimation to a threshold;
- and
- in response to the first estimation not satisfying the threshold:
- disable, by the decision circuit, the first filter;
- enable, by the decision circuit, a second filter;
- generate, using the second filter, a second estimation of the symbol;
- and
- decode the symbol using the second estimation instead of using the first estimation.
