| Abstract: | 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. |
