摘要 IEEE802.16协议采用的OFDMA技术提供了两种子信道使用方式,分别为FUSC和PUSC,结合FUSC的固有结构特点,对导频配置方法和采样钟同步算法进行更深入的优化,提出了一种更精确的载波和采样钟同步方案。仿真结果表明,此方案所得到的载波同步估计值比普通算法更加准确,同步性能也随之有了很大的改善。 IEEE 802.16 OFDMA system supports two usages of subchannels, FUSC and PUSC. In this paper a reliable carrier and sampling frequency synchronization scheme for PUSC is presented. And a symmetrical pilot allocation structure is proposed. The simulations show the robustness is checked in muhipath channel.
