Abstract
Physical layer devices and related methods for determining Bit Error Rates (BERs) and correcting errors in signals received through shared transmission media of wireless local area networks are disclosed. A physical layer device is configured to identify coding violations in received signal, determine a rate of the coding violations in the signal, and estimate a BER of the signal to be equal to the determined rate of the coding violations. A physical layer device is configured to invert a half symbol immediately preceding or immediately following a coding violation based, at least in part, on signal integrities of the half symbol immediately preceding and the half symbol immediately following the coding violation to correct a bit error.
