Diversity reception system for motor vehicle, initiates selected reception signal repeatedly, so that level of reception signal is adjusted and updated for several times within specific distance

摘要

An antenna system has control logic switch (2) switched to different positions for receiving signals at a connection point. A testing device (25) is designed, so that when its input is initiated by symbol cycle generated in a receiver (3), the reception level is determined within shortest possible level testing duration (Tp). A favorable reception signal is repeatedly initiated, to adjust and update level of the reception signal multiply within a specific distance.
