摘要 提出了一种改进的基于m序列的循环相关信道估计算法,将此算法应用于单载波频域均衡系统中,并在广播频段中的波段Ⅲ进行了仿真实验。仿真结果表明,此算法在保持低运算复杂度的同时,提供了良好的信道估计性能和较好的系统传输性能,验证了单载波频域均衡技术在广播领域中应用的可能性。 This paper presents an improved circular correlation channel estimation algorithm based on m-sequence.We simulate this algorithm in the SC-FDE system in brand III.The results prove the applicability of SC-FDE in broadcasting,and show that this algorithm has lower complexity and acceptable performance on channel estimation and transmit.
