摘要： A method (600) and devices for enhancing the performance of one or more antennas (440) is provided. A control circuit (104) assesses performance of an antenna (101) in a plurality of bands, such as a receive band and a transmit band. The control circuit (104) then selects one of the bands, e.g., a lesser performing band, as a “selected band” for which the antenna (101) will be optimized. The control circuit (104) can then adjust an adjustable impedance matching circuit (103) coupled to the antenna (101) to improve the efficiency of the antenna (101) in the selected band and can adjust a resonance of the antenna (101) to further improve an efficiency of the antenna (101) in the selected band.

摘要： A method and system provides an automatic frequency correction (AFC) within a wireless communication device. A synchronization controller estimates first and second frequency errors respectively associated with a first received signal corresponding to a first receiver path and a second received signal corresponding to a second receiver path. The synchronization controller determines a value and a type of target clock of a first AFC associated with the first frequency error. If the first AFC is not generated to target a shared clock such as a reference clock, the synchronization controller generates a second AFC to compensate for the second frequency error. However, if it is determined that the first AFC targets a shared clock, the synchronization controller generates the second AFC to compensate for the first AFC and the second frequency error. The synchronization controller synchronously applies the first and second AFCs to the relevant clocks.

摘要： A method and system performs antenna tuning to minimize interference affecting signal reception within a wireless communication device. An antenna tuner controller determines whether the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation. In response to determining that the wireless communication device concurrently provides the simultaneous signal transmission and reception and the dual signal propagation, the antenna tuner controller determines a current mode of operation corresponding to simultaneous signal transmission and reception and the dual signal propagation. Based on the mode of operation determined, the antenna tuner controller identifies a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device actively communicates within the specific mode of operation. In response to the identifying the priority for performing antenna isolation, the antenna tuner controller performs antenna impedance tuning that provides antenna isolation corresponding to the priority.

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.
