ANTENNA SWITCHING RECEPTION SYSTEM AND WIRELESS COMMUNICATION DEVICE COMPRISING THE SAME

PROBLEM TO BE SOLVED: To reduce the effect of level variation due to multipath fading in an antenna switching reception system even under an environment where a number of multipaths exist.SOLUTION: While switching is performed between a plurality of antennas with a predetermined period (#1), a wireless signal transmitted from a transmission system is received (#2). The received signal is down-converted and demodulated (#3, #4), and bit synchronization is established (#5). After that, a unique word UW1 is detected (#13, #22), and a signal quality of the unique word UW1 is detected (#14, #23). After that, switching is performed between the antennas (#15, #24), a unique word UW2 is detected (#17, #26), and a signal quality of the unique word UW2 is detected (#18, #27). After that, the detected signal qualities of the unique words UW1, UW2 are compared, and a later payload is received by an antenna with the better signal quality (#8).
