1. A method of processing radio-frequency (RF) signals in an RF receiver using multiple switched antennas, the method comprising:
detecting a packet;
estimating and storing a carrier frequency offset (CFO) value; and
averaging CFO values and removing the CFO depending on whether an antenna switch count exceeds a threshold.
