Abstract
A communication device can be configured to detect false positives of a decoded signal that have passed error detection. The communication device can include an error detector and a false positive detector. The error detector can detect an error of a decoded signal generated from an encoded signal, and output a payload of the decoded signal in response to the decoded signal passing the error detection. The false positive detector can calculate an estimated bit-error rate (BER) of the encoded signal and a predicted BER of the encoded signal. The false positive detector can determine a false positive of the error detection passing of the decoded signal based on the estimated BER and the predicted BER.
Claims22
A communication device operable to receive an encoded signal, comprising:
- an error detector configured to detect an error of a decoded signal generated from the encoded signal;
- and
- a false positive detector configured to determine a false positive of the decoded signal having passed error detection by the error detector based on an estimated bit-error rate (BER) of the encoded signal and a predicted BER of the encoded signal.
A communication device operable to receive an encoded signal, comprising:
- a transceiver configured to generate a decoded signal from the received encoded signal;
- and
- a controller that includes:
- an error detector configured to detect an error of a decoded signal generated from the encoded signal;
- and
- a false positive detector configured to determine a false positive of the decoded signal having passed error detection by the error detector based on an estimated bit-error rate (BER) of the encoded signal and a predicted BER of the encoded signal.
