摘要： A method for computing a gain control metric used in controlling gain in a wireless repeater operates to store correlation and normalization values associated with the gain control metric for the previous N samples in registers. For each new sample of the gain control input signal, the correlation and normalization values are computed by discarding the multiplication terms of the obsolete sample and adding the multiplication terms of the new sample to the stored correlation and normalization values. In this manner, the complexity of the computation is greatly reduced and the complexity of the computation does not increase with the integration length.

摘要： A method for monitoring feedback loop stability in a wireless repeater includes measuring a gain control metric in the feedback loop of the repeater periodically for a given time period where the gain control metric is indicative of a loop gain of the feedback loop of the repeater; and monitoring the magnitude of the gain control metric to determine the stability of the feedback loop of the repeater.

摘要： A wireless repeater introduces a low level noise to the signal path of the repeater where the introduced noise is used to facilitate channel estimation. The introduced low power level noise may be added to the receive signal or to the transmit signal. The low power noise signal ensures that the repeater always has a reference signal for performing channel estimation, even when the repeater is not receiving any incoming signal traffic. In one embodiment, a low noise signal is inserted to the transmit circuit of the repeater. In another embodiment, the repeater is configured to increase the noise figure of the receive circuit where the detected noise figure acts as a receive signal.

摘要： A method for controlling gain in a wireless repeater includes computing a gain control metric indicative of a loop gain of the repeater and detecting changes in a signal power of a gain control input signal where the gain control input signal is taken from any point in the feedback loop of the repeater. When a large power swing in the gain control input signal is detected, the method operates to discard at least a portion of each gain control metric measurement for a first duration before continuing with computing the gain control metric. In another embodiment, the method may include discarding samples of the gain control input signal used in computing the gain control metric for a first duration when a large power swing in the gain control input signal is detected.

摘要： A wireless repeater incorporates a gain management block to implement a multi-parameter gain management algorithm. The gain management algorithm receives gain settings from at least a gain control metric for stability and output signal quality and signal headroom values associated with circuitry of the repeater. The gain management block provides secure and robust boot-up of the repeater as well as oscillation detection and prevention. Furthermore, the gain management block implements repeater stability control, output signal-to-noise level control, uplink and downlink gain balance control and compensation for device constraints.
