    摘要: An embodiment of the invention provides a method for effecting switchback on a spatial division multiple access (SDMA) PHS channel. A communication signal is broadcast over each of one or more SDMA channels of a multi-access channel to one or more corresponding user terminals. A set of transmit spatial weights is determined for a synchronization burst to a user terminal attempting to reestablish communication over an SDMA channel of the multi-access channel. The set of transmit spatial weights is determined such that interference caused by one or more communication signals to the synchronization burst is reduced.

    摘要: Embodiments of the invention provide various methods for detecting a spatial division multiple access (SDMA) channel swap. A first SDMA communication channel is assigned to a first user terminal that initially transmits its signal over the first SDMA communication channel. A second SDMA communication channel is assigned to a second user terminal that initially transmits its signal over the second SDMA communication channel. The first user terminal's signal and the second user terminal's signal are analyzed to determine that the first user terminal is transmitting its signal over the second SDMA communication channel and the second user terminal is transmitting its signal over the first SDMA communication channel.

    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: 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.
