发明名称 Diversity receiver
摘要 A diversity receiver with simplified construction, excellent receiving signal quality even with very low fading speeds wherein, on the basis of a signal from a receiving unit capable of detecting the receiving signal intensity, an antenna changeover is effected when the receiving signal intensity falls below a changeover threshold value. When, at the termination of a first lapse time from the first antenna changeover, the receiving signal intensity is below that immediately before the first antenna changeover, an antenna changeover is again effected and any antenna changeover is prevented from being effected for a second lapse time from the second changeover. The second lapse time is set to be longer than the first lapse time.
