    摘要: Embodiments of a repeater environment can be operative to deploy a feedback cancellation loop that is adaptively coupled with an antenna array such that a selected metric can be applied to the antenna array and feedback cancellation loop combination to improve signal integrity and amplification. Illustratively, the feedback cancellation loop of the exemplary repeater can be adapted by a metric that operatively adapts weights provided by performing a selected linear algebra technique to the feedback cancellation loop such that the metric can be indicative of the level of transmitter signal present at a receive and can be derived based on performing a correlation between the transmitted signal and the receiver signal. Further, operatively, the exemplary repeater can maintain a delay sufficient to preferably ensure that transmitted signal is de-correlated with the desired receiver signal, and time aligned and correlated with the feedback leakage signal.

    摘要: Methods and systems are provided to generate digital coefficients for a filter. The generation of coefficients relies on a Fourier transformation of an impulse response in time domain that is zero padded, e.g., zeros are appended to an array corresponding to a sampled input signal of length M. A unit prototypical filter is generated through a frequency domain response of length NFFT=NS+M−1, wherein NS is a sampling length of the incoming signal. The unit prototypical filter is then circularly shifted in order to generate a band pass filter centered at a desired frequency. Circularly shifted filters are point-to-point added to generate a set of composite digital coefficients to filter the incoming signal. The reference frequencies for the composite filter are extracted from a message received from one or more base stations associated with one or more service providers. The composite filter typically operates on a frequency repeater.

    摘要: A repeater (200) facilitates wireless communication between a first communication device (100) and a second communication device (105) in a wireless network using a time division duplex protocol for data transmission. The repeater (200) includes a receiver (310, 315) for receiving a signal on either of at least two bi-directional communication frequencies simultaneously. A signal detector (362) is operatively coupled to the receiver (300, 310, 315) for determining if the signal is present on at least one of the two bi-directional frequencies. A frequency converter (320, 321, 323, 324, 360, 361) is for converting the signal present on one of the bi-directional frequencies to a converted signal on the other of the bi-directional frequencies. A transmitter (300, 325, 330, 335, 345, 350) is for transmitting the converted signal on the other of said bi-directional frequencies.
