| 摘要 |
The present invention discloses a baseband chip and a method to implement multi-mode switching for a mobile terminal based on the baseband chip, the baseband chip of the mobile terminal in the present invention includes three subsystems of a source encoding/decoding subsystem 102, a wireless transmitting/receiving subsystem 101, a wireless transmitting/receiving and source encoding/decoding common control and process subsystem 100, the baseband chip may be implemented by using a single chip based on CMOS technology. The baseband chip of the present invention are suitably used to a TD-SCDMA mode mobile terminal or a multi-mode mobile terminal including TD-SCDMA, the new requirements proposed to the mobile terminal of the third generation mobile communication technology are met, and repeated design are decreased; furthermore, the method of switching among different communication modes for the mobile terminal based on the above mentioned baseband chip in the present invention implements the switching among different communication modes for the mobile terminal. |
