摘要
提出了一种改进的LMS算法,使基于该算法的半盲自适应信道均衡器适用于时变信道中OFDM系统。在DVB-T信道和WSSUS信道中对该算法进行仿真,结果表明该LMS算法对选择性衰落信道和移动信道都具有很好的跟踪性能。
An improved LMS Algorithm is presented in this paper,based on which there is a semi-blind adaptive equalizer of time-variant channel for OFDM systems.The simulation for the algorithm will be executed in two kinds of channel:chan-nel for DVB-T system and WSSUS channel.The results show that the improved algorithm has good performance for tracking selective fading channel and mobile channel.[
