Abstract

A communication system has a base station having an adaptive antenna with a plurality of main array antenna elements for generating a plurality of communication beams. The system further includes a gateway station coupled to the base station. The gateway station forms a plurality of beams commands by communicating plurality of a control signals to the base station to form the communication beams.

Claims (5)

1. A communications system for communicating with mobile user terminals comprising: a base station having an adaptive antenna with a plurality of panels, each of the plurality of panels arranged to have a different field of view, each panel having a plurality of main array antenna elements for simultaneously generating a plurality of dynamic communication beams that move with the mobile terminals; and a gateway station coupled to said base station, said gateway station forming a plurality of beams commands for each of the plurality of panels by communicating a plurality of control signals to the base station to form the plurality of dynamic communication beams further comprising a limiter coupled within a feedback path.

2. A communications system for communicating with mobile user terminals comprising: a base station having an adaptive antenna with a plurality of panels, each of the plurality of panels arranged to have a different field of view, each panel having a plurality of main array antenna elements for simultaneously generating a plurality of dynamic communication beams that move with the mobile terminals; and a gateway station coupled to said base station, said gateway station forming a plurality of beams commands for each of the plurality of panels by communicating a plurality of control signals to the base station to form the plurality of dynamic communication beams further comprising a nulling processor, wherein said nulling processor comprises an element code despread and a user code despread.

3. A communications system as recited in claim 2 wherein said nulling processor comprises a weighted feedback loop coupled to an output signal.

4. A communications system as recited in claim 2 wherein said nulling processor comprises auxiliary elements coupled to an output signal.

5. A communications system for communicating with mobile user terminals comprising: a base station having an adaptive antenna with a plurality of panels, each of the plurality of panels arranged to have a different field of view, each panel having a plurality of main array antenna elements for simultaneously generating a plurality of dynamic communication beams that move with the mobile terminals; and a gateway station coupled to said base station, said gateway station forming a plurality of beams commands for each of the plurality of panels by communicating a plurality of control signals to the base station to form the plurality of dynamic communication beams, wherein said base station comprises a user code despreading circuit coupled to an element code despreading circuit which is coupled to said main array elements.
