Synchronization on reverse link of mobile mode communications systems |
摘要 |
Methods and apparatus are disclosed to provide orthogonal multiple access communication in a return link of a satellite communication system. In one embodiment, a closed loop control of a transmit parameter associated with transmission of signals may be performed. In addition, changes in motion of a terminal are monitored such that an open loop control of the transmit parameter is performed, if the detected change meets a certain threshold. For example, an open control is performed if an abrupt or sudden motion is detected.
