Embodiment Construction
[0033] figure 1 is a flowchart of the method of the present invention.
[0034] figure 2 It is an implementation block diagram of the present invention applied in WCDMA system. It includes: an array element (21), an uplink channel (22), an uplink beamforming (23), a baseband processing (24), a downlink beamforming (25), and a downlink channel (26).
[0035] Space signals enter the uplink channels 2201...2212 from the antennas 2101...2112, and the generated IQ baseband signals enter the uplink beamforming 231...233, and output 12 sets of beam domain signals, and the 12 sets of beam domain signals directly enter the 12 inputs of the baseband processing chip. After the downlink data enters the baseband processing chip, it is output to the corresponding output according to the information of the uplink data, enters the downlink beam forming 251...253, and then enters the antenna elements 2101...2112 through the downlink channel to be emitted.
[0036] The array structure adopt...
