The Smart Phone Based On Independent Ap Architecture Digital Baseband Signal Processing Method And Realization

The functionality of the mobile phone evolves from communication-only to voice, audio, video and multimedia capability with the development of communication industry. With the increasing of battery capacity, integration capability of CMOS circuit, communication bandwidth and CPU core frequency, the phone is able to make more and more complicated features available. The system designer faces much more challenges to be able to succeed in integrating all these new features together.The thesis introduces the hardware design of the smart phone which is based on the new 3G communication technique. Firstly, the digital baseband processing theory is given, Secondly, evaluation is made based on the independent AP hardware architecture, then a modular design is introduced, which includes the memory module, display module, audio module, power management and Li-ion battery gas gauge, data transmission module, radio module design.Finally, I verified the design by testing antenna sensitivity, Multimedia performance, data throughput, signal quality and firmware BSP stability, all of which ensures high product quality, and we get a good feedback from market.
