  • Patent number: 10075202
    Abstract: Methods and apparatus are provided for detection path design for reflection coefficient estimation. In one novel aspect, a hardware-based phase estimator estimates a phase shift between the forward path signal and the reverse path signal. In one embodiment, a data selector is used to pass only signals above a magnitude threshold. In another embodiment, a modified phase unwrap algorithm stores an unwrapping correction for subsequent samples and updates the stored unwrapping correction upon processing of each sample processed. In another novel aspect, mixed hardware and software solutions are used. In one embodiment, the reference signal and the detection signals are matched such that the modulation signal interference is removed. In some embodiments, one or two power detectors and a cross-correlator are used. In yet another embodiment, two detection measurement paths are used to obtain the reflection coefficient. In one embodiment, fractional timing offset is estimated to obtain the reflection coefficient.

  • Patent number: 9654059
    Abstract: An impedance tuning control apparatus has a processing circuit and an output circuit. The processing circuit determines a first control setting according to a first performance metric, and performs a search operation with a search start point set by the first control setting to find a second control setting according to a second performance metric. The second performance metric is different from the first performance metric. The output circuit outputs a final control setting to a tuner, wherein the final control setting is derived from the second control setting.
