Embodiment Construction

[0023] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0024] FIG. 2 is a block diagram of an embodiment of a receiving device in a mobile terminal with multiple antennas using a TD-SCDMA system according to the present invention. Compared with the existing receiving device of a mobile terminal with a single antenna, a multi-antenna (MA) module 600 is added in the receiving device shown in FIG. 2 , and the delay generated by the MA module 600 is very small, so it can be ignored The delay brought by the MA module 600.

[0025] Specifically as shown in Figure 2, the receiving device includes: two antennas 100, 101, an MA module 600, a radio frequency signal processing module consisting of an RF module 200 and an ADC / DAC module 300, and a baseband physical layer processing A baseband processing module composed of module 400 and a baseband high-level processing module 500. Wherein, the two antennas 100, 101 are us

Abstract

The 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.
