Embodiment Construction
[0053] Such as figure 1 Shown, the CDMA communication system of a preferred embodiment of the present invention under DTX or the smart antenna realization device of HSDPA mode comprises:
[0054] 1) Antenna array (101)
[0055] 2) Multi-channel amplification unit (102)
[0056] 3) Multi-channel transceiver unit (103)
[0057] 4) channel estimation unit (104)
[0058] 5) Uplink baseband processing unit (105)
[0059] 6) Shaped weight generation unit (106)
[0060] 7) Downlink beamforming unit (107)
[0061] For the uplink, the multi-channel amplifying unit (102) works in a low-noise amplifying mode, and the wireless signal is received by the antenna array (101), amplified by the multi-channel amplifying unit (102), and then transmitted to the multi-channel transceiver unit (103 ); the multi-channel transceiver unit (103) converts the radio frequency signal into a digital baseband signal after filtering, down-conversion, analog-to-digital conversion, etc.; the multi-channe...
