    Abstract: A communications system improves performance of detecting a signal having an indication of a request to change communications states by making at least two positive identifications of the request in a given time frame. The system may further improve performance by applying a difference in power levels for a non-request state (i.e., steady state or ‘control hold’ state) versus a request state (i.e., ‘request to change’ state). In one particular application, a base station determines a request to change communications states with a reasonably high probability of detection and a reasonably low probability of false detection. The system has a reduced number of erroneous communications states, such as erroneous traffic channel allocations. The detection technique is compatible with 1xEV-DV systems and I-CDMA systems, but general enough to support systems employing various other communications protocols used in wired and wireless communications systems.

    Abstract: A downlink communication is transmitted/received in at least one downlink time slot. In response to the received downlink communication, an acknowledgement message is received/transmitted in an uplink time slot a fixed integer number of uplink time slots after transmission/reception of the received downlink communication. The uplink and downlink time slots are staggered by substantially a half of a time slot.

    Abstract: Methods and systems are provided to configure a frequency repeater. The frequency repeater is configured with an identity of a service provider and receives a message that defines a set of frequencies to be repeated, the frequencies are associated with a service provider that matches the preconfigured identity. A digital filter receives an incoming signal from the service provider, and filters and repeats the frequencies defined in the received message. The frequency receiver can also determine a set of frequencies to be filtered and repeated based on a cell search procedure performed with a modem that resides in the repeater. A policy established by the service provider can also be utilized to facilitate defining the set of figures to be repeated. By utilizing a signal quality metric and an isolation metric associated, with the performance of a receive and transmit antenna utilized by the repeater, the set of frequencies to be filtered and repeated can be adapted in real time.

    Abstract: 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.

    Abstract: 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.
