Abstract
A symbol error detector can be configured to detect symbol errors of a Bluetooth enhanced data rate (EDR) packet without relying solely on a CRC error detection mechanism. After a phase of a current symbol is demodulated to determine a demodulated current symbol, the phase of the demodulated current symbol can be subtracted from the phase of the current symbol prior to demodulation to yield a phase error. The phase error can be compared against a phase error threshold to determine a potential unreliability of the demodulated current symbol. The phase error being greater than the phase error threshold can indicate that the demodulated current symbol may be unreliable. Accordingly, a symbol error notification can be generated to indicate that the demodulated current symbol may be unreliable.
