摘要
目前宽带无线通信系统主要有正交频分复用(OFDM)技术以及单载波频域均衡(SC-FDE)技术,随着研究的深入,SC-FDE技术越来越得到人们的关注。文章使用simulink工具分别对这两种通信技术在THz频段信道特征下进行仿真。通过理论分析和仿真实验研究了这两种通信系统在不同条件下的表现,说明了SC-FDE系统在宽带无线通信中应用的可行性,为区分OFDM和SC-FDE系统在不同信道条件下的实际应用范围提供了理论依据。
At present,Orthogonal Frequency Division Multiplexing（OFDM） is widely used in high-speed communication systems,and the Single Carrier Frequency Domain Equalization（SC-FDE） is getting more attention.Simulations have been done with both communication technologies with indoor wireless channel condition with Simulink tools.rom theoretical analysis and simulation result,the performances of both technologies in different conditions are studied.Showing the possibility of using SC-FDE in WBCS applications,and provide theory evidence on the using range of OFDM and SC-FDE system with different channel condition.
