摘要:
A method, transceiver integrated circuit (IC), and communications device for generating antenna tuning states derived from a pre-established trajectory of tuning states to adjust a detected signal level towards a preset, given value. A tuning state generation (TSG) controller determines whether a detected signal level matches a given value. If the detected signal level does not match the given value, the TSG controller selects an initial preset tuning state from a pre-established trajectory corresponding to a pre-identified operating condition that best matches a current operating condition. The TSG logic forwards the initial preset tuning state to the antenna tuner to trigger impedance transformation. Following generation of the initial preset tuning state, the controller receives an updated detected signal level. If the updated detected signal level fails to match the given value, the controller generates an incremental tuning state that is interpolated between the initial and a final preset tuning states.
