Method for optimizing of communication signal

摘要

A transceiver that reduces power consumption when data is transferred between devices in different modes. The transceiver is arranged in a first node and in a second node, which communicate between each other. A first control unit generates a first signal transmitted from the first node in predetermined time intervals during a first period that establishes an environment for communication between the first node and the second node. The second node transmits a second signal transmitted in response to the first signal. The first control unit generates a third signal upon detection of the second signal. A second control unit gradually decreases amplitude of the first signal based on the third signal to set the amplitude of the first signal to a predetermined amplitude so that the second node is receivable of the first signal.
