    摘要: A method and apparatus for medium access control in a receiver is shown, involving frequency hopping through each of a plurality of channel frequencies for the receiver, monitoring a baseband section of the receiver using a data quality detector (DQD) circuit configured to assert a DQD signal when valid data is sensed at the output of a demodulator of the receiver, waiting a first preset period of time after changing the channel frequency for each frequency hop and monitoring whether the DQD signal is asserted, resuming frequency hopping if the DQD signal is not asserted within the first preset period of time, and maintaining a current channel frequency in order to receive a data packet if the DQD is asserted.
