摘要
均衡技术是克服多径变参信道衰落的一种有效手段,也是宽带无线通信中对抗多径的一种重要方法。从设计原理出发,进行了单载波频域均衡(SC-FDE)的设计,分析了单载波均衡的技术特点,并与多载波OFDM技术在通信容量、PAPR等方面进行了比较,最后在莱斯信道进行了仿真分析,给出仿真结果,表明单载波频域均衡系统能够获得较好的性能,降低误码率。对系统工程设计有一定的借鉴意义。
The equalization technology is an effective means to overcome muhipath and variable parameter propagation fading, and is an important means to resist multipath fading in broadband wireless communications. This paper designs SC-FDE with the design principles, analyzes the technical features of SC-FDE and compares its message capacity, PAPR, etc. with that of multicarrier OFDM technology. Finally the simulation analysis is made at Rayleigh Fading Channels, and the simulation results show that SC-FDE system can obtain a better performance and lower bit error rate. It has some meaning of reference for system engineering design.
