WIRELESS COMMUNICATION APPARATUS WITH MULTI-ANTENNA AND METHOD THEREOF

摘要

This invention proposes a wireless communication apparatus and its method. The wireless communication apparatus comprises: multiple antennas, a multiple-antenna signal processing module, a RF signal processing module and a baseband processing module. The multiple-antenna signal processing module is designed to combine multiple RF signals received from the multiple antennas into a single RF signal. The RF signal processing module is designed to convert the combined single RF signal into a single baseband signal. The baseband processing module is designed to perform baseband processing on the single baseband signal. This wireless communication apparatus realizes a multi-antenna system by simply inserting a multiple-antenna signal processing module into a typical single­antenna system. Both the RF signal processing module and baseband processing module of existing single-antenna system remain unchanged. Therefore, the redesign process is greatly simplified, which results in remarkable reduction of design difficulty and implementation cost.
