    摘要: Methods and apparatus for calculating spatial processing strategies in adaptive antenna array processing systems. Reference signal quality, intersymbol interference, data processed and received signal quality can be determined by burst type or remote device type and used to determine a synthetic signal level for use in developing a spatial processing strategy. A synthetic signal have an isotropically distributed component can be added to the antennas in the array or the diagonal elements of the received signal covariance matrix to develop uplink and downlink spatial processing strategies. Different synthetic signals at different signal levels can be used to develop different uplink and downlink spatial processing strategies. The downlink signal level can be larger than the uplink signal level. Uplink and downlink processing strategies can be developed in substantially the same way.

    摘要: Channels are assigned based on co-spatial constraints in wireless network using spatial division multiple access. In one example, the invention includes assigning a co-spatial constraint to each of a plurality of conventional traffic communications channels of a base station, and receiving a request from a user terminal to communicate using a traffic communication channel of the base station. The invention further includes measuring a quality parameter of the request deriving a co-spatial constraint for the user terminal, assigning the user terminal co-spatial constraint to the user terminal, and assigning the user terminal to a traffic communication channels having a channel co-spatial constraint that is no less than the user terminal co-spatial constraint and that has no more assigned radios than permitted by the channel co-spatial constraint.

    摘要: The present invention can improve efficiency in wireless radio networks using spatial division multiple access (SDMA) strategies. One embodiment of the invention includes determining a quality parameter of a user terminal based on a signal received from the user terminal at a base station. One embodiment further includes determining a co-spatial constraint on the user terminal based on the quality parameter, the co-spatial constraint comprising a limitation on the quantity of additional user terminals with which the user terminal can share a conventional communications channel.

    摘要: A method and apparatus for distinguishing between two or more signals, each associated with a particular remote user terminal, in a shared-channel wireless communication system. A communication device, for example, a base station, causes an offset (e.g., a time and/or a frequency offset) between the transmission of first and second uplink signals that simultaneously occupy the same channel and that are transmitted by first and second remote user terminals, respectively. According to one aspect of the invention, the offset is relatively small enough such that the first and second uplink signals remain within the same channel, but relatively large enough such that based on the offset, the communication device may identify that the first uplink signal is associated with the first remote user terminal.

    摘要: A method and apparatus for mitigating co-channel and inter-channel interference in an antenna array system. According to one aspect, the channel-select filter of a base station or other communication device is modified to detect inter-channel interference on at least one non-primary channel when the transmitter is communicating with a remote user terminal on a primary channel. The spatial characteristic of the interference is determined and used to obtain a weight that mitigates the inter-channel interference. According to another aspect, the spatial characteristic of co-channel and/or inter-channel ghost signal interference caused by a transmitter is determined and used to mitigate the effects of such interference.

    摘要: The present invention allows many of the benefits of spatial diversity to be realized in a hopping radio communications system. One embodiment of the invention includes transmitting signals from a first radio using a first hopping sequence and transmitting signals from a second radio using spatial processing and a second hopping sequence. The second hopping sequence is coordinated with the first hopping sequence. In another embodiment, the invention includes selecting a set of spatial processing parameters based, at least in part, on a determination whether a third radio using a first frequency resource during a first time interval uses a second frequency resource during a second time interval and transmitting a signal from a first radio to a second radio during the second time interval using the second frequency resource and the selected set of spatial processing parameters.
