摘要
介绍了单载波频域均衡技术的原理,与单载波时域均衡以及多载波OFDM系统进行了比较。该技术结合了两者的优点:能有效对抗多径信道,且具有较低的复杂度;降低了峰均比和对载波频偏、相位噪声的敏感性,因而在无线通信领域具有广阔的应用前景。
This paper introduces the theory of Single Carrier Frequency-Domain Equalization （SC-FDE）, and compares the SC-FDE system with Single Carrier Time-Domain Equalization （SC-TDE） system and OFDM system. SC-FDE combines the advantages of the both technologies. It can resist the multipath efficiently, have a low complicacy; reduce the PAR （peak to average power ratio） and the sensitivity to both Carrier Frequency Offset and Wiener Phase Noise. Thus, SC-FDE has a bright future for application in wireless communication.
