发明名称 Self-aligning vehicular transmitter system
摘要 A method is provided for self-aligning a transmitting frequency between a portable transceiving device and a base station transceiving device. A test signal is transmitted from one of a portable or base station transceiving devices to the other of the portable or base station transceiving devices. The test signal has a frequency that varies during the transmission. The varying of the frequency of the test signal generates a plurality of discrete signals. The other of the portable or base station transceiving devices measures a RSSI value of each discrete signal. The other of the portable or base station transceiving devices determines a discrete signal having a maximum RSSI value. At least a portion of a subsequent message from the other of the portable transceiving device or the base station transceiving device is transmitted at an optimum frequency used for the test signal identified by the test result signal.
