摘要
跳频通信系统具有较强的抗干扰能力;OFDM具有较高的频谱利用率;将二者的优点结合,文中提出了FH-OFDM通信系统,同时也针对跳频环境下的OFDM同步问题,给出一种最大似然估计同步算法,并进行了仿真分析。
The paper presents the FH-OFDM system with the joint of the stronger ability against interference in frequency-hoppad system and greater spectral efficiency in OFDM system. In the paper, it applies the synchronic algorithm based on maximum likelihood estimation for the synchronization in FH-OFDM communication system and carries out performance through computer simulations.
