2148918 9413068 PCTABScor01 The present invention comprises a method and apparatus for selecting one of at least two antennas (202, 204) in a communication unit (200) for use in a wireless communication system (100). A signal is received by a radio frequency receiver during a receiving period from one of the at least two antennas (202, 204) currently selected by an antenna switch (206), the signal having a plurality of bits. The receiver is capable of determining the quality of the receive signal by determining if the incoming bits transition periods fall within a predetermined time window. If it is determined by the receiver that the quality of the receive signal is below a predetermined threshold the currently selected antenna (202 or 204) is switched.
