DTMB Receiver Technology Implementation Based On The SORA Software Radio Platform

With the development of modern information technology, the transmission speed of the wireless communication technology ever-increasing demands. In order to research and application igh-speed wireless communication protocols or standards related technology. We can research wireless communication protocol in software radio platform. So have a great advantage in terms of time and cost, is conducive to new technologies or new products to market faster.However, the traditional software radio platform can not achieve high-speed wireless communication protocol, the maximum transmission rate of a few hundred kbps, can not meet the wireless communication protocols and standards,for example1802.11, digital television standard transmission speeds of up to more than10Mbps. In order to achieve high-speed wireless communication protocol in software radio platform, there are some difficulties in the design of the platform. The paper mainly focus on the design to meet the high-speed wireless communication system software radio platform Sora and experiment on the platform on the implementation of the digital TV standard DTMB.Sora is a commercial computer-based reconfigurable software radio platform. Give full play to the performance and flexibility of a general-purpose processor, the use of hardware and software combined optimization techniques to meet the challenges of the high-speed signal processing. So you can use the software radio platform to quickly achieve the the DTMB wireless communication protocol parameters can be modified by software without modifying the hardware platform you can quickly see the signal processing performance under different technical parameters.The thesis work includes:1) A brief introduction to the development of digital television, the foreign technical characteristics of the digital television system, a detailed study of the key technology of digital television. MATLAB simulation analysis on channel equalization of the digital TV technology, software radio platform test to prepare for the back. 2) the detailed description of the work of the RF control panel of the platform RCB hardware design, including schematic design, choice of chips, printed circuit board design and final stability considerations, DDR2controller design, simulation, and Application.3) the processing of the pictures or videos into the TS data stream, and then Sora software radio platform according to the DTMB standard for data transmission. And monitoring software for real-time observation technical parameters.
