    摘要： Systems and methodologies are described that facilitate guard bandwidth independent mapping and de-mapping of bandwidth in a wireless communication system. Broadcast signals can be created as if all bandwidth were available, and guard bandwidth can be initialized over the utilized bandwidth such to puncture the data existing in the guard bandwidth. Upon decoding the broadcast signal, size of the guard bandwidth can be predetermined or estimated allowing a center portion of the signal to be decoded without decoding the guard bandwidth. In this regard, the decoder of the signal need not find exact positions of the guard bandwidth as transforming and decoding the center portion can provide a substantial portion of the signal to interpret the signal.

    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. In operation, a large magnitude of the gain control metric indicates instability in 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.
