Abstract: A Bluetooth receiver is provided. The Bluetooth receiver comprises interface circuitry configured to receive a receive packet. Further, the Bluetooth receiver comprises physical layer processing circuitry configured to demodulate the receive packet into a bit stream representing a sequence of data symbols. Further, the physical layer configured to determine a number of bits in the bit stream having a highest likelihood of being erroneous as weak-bits and determine locations of the identified weak-bits in the bit stream. The Bluetooth receiver further comprises medium access control layer processing circuitry configured to receive the bit stream and information about the determined locations of the identified weak-bits from the physical layer processing circuitry. Further, the medium access control layer is configured to flip one of the weak-bits and a sequential bit in the bit stream in order to generate a modified bit stream, run a respective cyclic redundancy check on the bit stream and the modified bit stream and compare results of the cyclic redundancy checks on the bit stream and on the modified bit stream.
