摘要
针对新一代5G波形的F-OFDM技术开展了研究,通过把一个宽带分为若干个子带,对每个子带进行滤波处理以实现更好的通信效能。基于Simulink平台进行了F-OFDM仿真系统的搭建,重点对F-OFDM符号同步方法和频偏估计方法进行了研究与仿真分析。实验结果表明,基于Chu序列相比采用PN序列可以获得更好的同步效果,基于导频的Classen频偏估计算法相比基于CP的CFO估计算法和基于训练序列的Moose估计方法可以获得更好的频偏估计效果。
F-OFDM,one of the new generation 5G waveform represent is researched.The wideband is divided into several subbands,and each subband can be filtered individually to realize better performance.The F-OFDM simulation system is set up based on Simulink platform.The symbol synchronization and frequency offset estimation method is analyzed and tested.The result shows that the synchronization method with Chu sequence achieve better synchronization performance than the method with PN sequence.The experimental result shows that Classen method with pilot has better estimation effect compared with the CFO method with CP and the Moose method with training sequence.
