Aperture synthesis communications system

摘要

A method and apparatus are provided for improving capacity in wireless communications systems for use in areas having a high user traffic density. For reception, signals received from an antenna array are processed by performing a transformation comprising aperture synthesis to map signal content received from the antenna array to at least one element of a plurality of elements in an image plane storage to produce a time series of values for the at least one element, and then by assigning the at least one element to at least one radio access transceiver of a plurality of radio access transceivers for receiving the time series of values from the at least one element. For transmission, at least one radio access transceiver of a plurality of radio access transceivers is assigned to at least one element of a plurality of elements in an image plane storage, the assignment providing for the at least one element to receive a time series of values from the at least one radio access transceiver, and then a transformation is performed comprising antenna synthesis to map the time series of values from the at least one element to the signals for transmission by the antenna array.
