<P>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. <P>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, when a unique word is detected (YES in #6), an antenna is fixed (#7), and a later payload is received (#8). <P>COPYRIGHT: (C)2013,JPO&INPIT |
