Abstract:
1. A method for determining a default gain of a wireless transmission system, the wireless transmission system comprising a signal transmission path and a signal feedback path, the signal feedback path being coupled to the signal transmission path, the signal transmission path comprising a power amplification circuit and a gain stage, the gain stage having a plurality of transmission gains; the method comprising: setting a gain of the gain stage as a specific transmission gain of the transmission gains; when the gain of the gain stage is set as the specific transmission gain, transmitting a plurality of test signals through the signal transmission path in sequence to generate a plurality of amplified test signals, wherein at least a portion of powers of the test signals correspond to the transmission gains, respectively; receiving the amplified test signals through the signal feedback path in sequence, and accordingly obtaining corresponding signal gains; and determining a default gain of the gain stage according to the signal gains.
