摘要:
研究了高清晰度数字电视(HDTV)中的频率同步及采样钟同步技术.对其中的小数倍频偏和采样钟偏移估计做了算法仿真分析,结合实际工程应用提出一种适用于数字视频地面广播(DVB-T)编码的正交频分复用(COFDM)调制系统的小数倍细频偏和采样钟偏移联合估计算法.并提出了相应的现场可编程门阵列(FPGA)实现方案,设计出的硬件电路经国家高清电视总体组(TEEG)的HDTV功能样机调试证明了该算法的易实现性和优良性能.
Abstract:
The frequency synchronization and sampling clock synchronization technique in high definition TV(HDTV)are investigated. Computer simulations have been made for decimal frequency and sampling clock offset estimation. An analysis and comparison for the performance of algorithms in accordance with engineering application are made. Also, a united estimation algorithm for fine decimal frequency and sampling clock offset is derived, which is suitable for digital video broadcasting-terrestrial(DVB-T)coded orthogonal frequency division multiplexing(COFDM)system. The corresponding field programmable gate array(FPGA)realizing scheme is proposed and the hardware circuit has been tested in the functional HDTV in team of engineering expert group(TEEG). Test result proves its easiness to be implemented and its excellent performance.
