SC-OFDM, a Low-Complexity Technique for High Performance Satellite Communications
نویسندگان
چکیده
Single-Carrier Orthogonal Frequency Division Multiplexing (SC-OFDM) is a transmission technique particularly suitable for satellite transmission due to its low envelope variations and to the advantages brought by its natural compatibility with zero roll-off. Moreover, low complexity per-carrier equalization is possible in the frequency domain. This paper proves the high performance of SC-OFDM transmission over satellite in different use cases and compares this performance with state of the art techniques such as DVB-SX transmission.
