In this paper, we focus on the radio resource management (RRM) issues in the two-hop Orthogonal Frequency Division Multiple Access (OFDMA) system with heterogeneous quality of service (QoS) requirements. To solve the RRM problem, we first propose a new two-hop frame structure to support the data relay operation from the base station to the relay station and cooperative transmission for the edge users...
In terrestrial wireless communications, high data-rate transmission can be readily achieved by installing base stations on the ground. However, the same system may not be adapted to maritime communication due to the geographically restricted nature of the sea, and therefore, MF/HF modems, capable of long-distance transmission, with low data-rate are frequently employed in maritime communication. Maritime...
