摘要 本文通过对欧洲数字视频地面广播调制方案的分析 ,结合计算机仿真和工程应用 ,深入研究了基于DVB -T标准、适用于编码正交频分复用 (COFDM )系统的信道估计算法 ,Matlab仿真及FPGA电路实现表明该算法具有可靠性高、复杂度低及易于实现的良好性能。 By analyzing the modulation scheme of the European Digital Video Broadcasting-Terrestrial , combining with computer simulation and engineering application, this paper makes a deep research on the channel estimation algorithm which is based on the DVB-T standard and suitable for COFDM system. Matlab simulation and FPGA circuit realization prove that the algorithm has such good performance as high reliability, low complexity and easy to realize.
