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 service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably, the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance subchannel.

摘要： A technique for implementing closed loop power control in a wireless system using a modulation that requires synchronization over the radio channel, which dynamically assigns coded channels on a demand basis. The technique maintains a proper power level, even when no traffic channels are allocated, by determining a link quality metric based upon the reverse link power received. This determination is made in response to a heartbeat signal sent at a rate which is only sufficiently fast to maintain code phase lock, for example, depending upon the expected maximum rate at which the subscriber unit will travel.

摘要： An adaptive antenna used in a receive only mode with a separate omnidirectional transmit antenna. The arrangement is especially effective for small, handheld wireless devices. The transmit antenna maybe integrated with the receive array by utilizing a horizontally polarized transmit and vertically polarized receiver ray. In other embodiments, the transmit antenna may be physically separate and not integrated with the receive array. In either case there is separate receive and transmit signal port as an interface to radio transceiver equipment. The use of an adaptive antenna in the receive only direction has the potential to increase forward links capacity to levels equal to or greater than reverse link capacity. This allows for a significant increase in the overall number of users that may be active at the same time in a wireless system.

摘要： A technique for allowing a first and second group of users to share access to a communication channel such as a radio channel. A first group of users is typically a legacy group of users such as those using digital CDMA cellular telephone equipment. The second group of users are a group of data users that code their transmissions in different formats optimized for data functionalities. The first group of users share one modulation structure such as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users share another modulation structure but in a manner that is consistent and compatible with the users of the first group. Specifically, the users of the second group may all use the same PN code and code phase offset. However, they are uniquely identified such as, for example, assigning each of them a unique orthogonal code.

摘要： A method for monitoring idling mode connections between a base station and idling subscriber units that are powered on, but not actively sending data, is provided. The method includes making available a plurality of orthogonal subchannels within at least one Code Division Multiple Access (CDMA) radio frequency (RF) channel. A shared orthogonal subchannel is assigned to at least two different idling subscriber units, but utilizing different time slots of the shared orthogonal subchannels. For each idling subscriber unit assigned the shared orthogonal subchannel, a respective heartbeat signal is sent within its assigned time slot at a data rate that is low enough to maintain bit synchronization with the base station. The respective heartbeat signals are tracked within the assigned time slots by selecting an assigned time slot within the shared orthogonal subchannel, retrieving a previous tracking of a respective heartbeat signal for an idling subscriber unit associated with the assigned time slot, determining a current tracking of the respective heartbeat signal for the idling subscriber unit associated with the assigned time slot, and updating the tracking of the idling subscriber unit associated with the assigned time slot based upon its current and previous trackings.

摘要： A technique for allowing a first and second group of users to share access to a communication channel such as a wireless radio channel is disclosed. The first group of users can be a group of legacy users such as those that use digital CDMA cellular telephone equipment based on the IS-95 standard. The second group of users can be a group of web surfers that code their transmissions using one of multiple formats. The first group of users can share one modulation structure such as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users can share another modulation structure, but in a manner that is consistent and compatible with the users of the first group. Specifically, the users of the second group may all use the same PN code and code phase offset. Each channel used by the second group of users can be uniquely identified by a corresponding unique orthogonal code.
