For the efficient use of frequency resources and high-speed data services@ multi-carrier based transmission techniques are considered as promising technologies for providing future radiocommunication services. This Recommendation presents an overview of multi-carrier based transmission techniques over satellite links@ briefly giving guidance for the utilization of multicarrier code division multiple access (MC-CDMA) and carrier interferometry orthogonal frequency division multiplexing (CI-OFDM) schemes for satellite radiocommunication systems.
