Embodiment Construction
[0074] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0075] This embodiment describes the application of the present invention in conjunction with the WCDMA system.
[0076] A smart antenna switching beam-adaptive secondary baseband receiving method, the method includes the following steps:
[0077] a: The smart antenna system receives wireless signals and converts radio frequency signals into baseband signals to be processed; including
[0078] a1: Receive wireless signals through the element of the antenna array and its corresponding antenna feed system, and output radio frequency signals;
[0079] a2: Use each corresponding radio frequency channel to process the obtained radio frequency signal, including power amplification, channel correction, demodulation and matched filtering, and output the baseband signal to be processed.
[0080] b: The output signal of step a is received and processed by the switch beam ...
