Research Of Mobile TV Technology Based On Embedded System

The popularization of Mobile TV project are based on many factors, whereas the most important is the Mobile TV technology. Based on the analysis of mobile TV technology issues and discussion of mobile TV standards, the thesis introduce the framework of the overall mobile TV terminals and focus on the design of the mobile TV terminals baseband chip and embedded Linux operating system of mobile phone TV.OFDM is one of the most important technologies of the mobile TV terminals baseband chip. OFDM technology is based on synchronization, channel estimation and the decoding algorithm. Not only matches the thesis related algorithms,but also simulate them by Matlab / Simulink tools. Therefor, the thesis provides a reliable data analysis for the settlement of mobile TV terminals baseband chip key technology.Embedded Linux characters of open-source. Based on it, the thesis makes the analysis and custom from the aspects of the Boot, Processing management, Compiling the kernel and Root file system, GUI.. And realize the prototype of the mobile TV phone operating system.
