    Abstract: An electronic device has a transmit circuit and a processing circuit. The processing circuit outputs a first portion of compressive sensing (CS) samples corresponding to a signal segment to another electronic device via the transmit circuit, and selectively outputs a second portion of the CS samples corresponding to the signal segment to another electronic device via the transmit circuit according to a response of another electronic device. In this way, a balance between the compression ratio and the reconstruction quality/speed can be achieved. Moreover, the signal reconstruction performed at the processing circuit may employ a multi-resolution/multi-scale reconstruction scheme to achieve a balance between the dictionary size and the reconstruction quality/speed, and/or may employ a multi-stage reconstruction scheme to achieve a balance between the reconstruction algorithm control setting and the reconstruction quality/speed. In addition, dictionary weighting, online dictionary update, and/or point constraints may be used to improve the reconstruction quality.

    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.

    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.
