ABSTRACT:
A novel and improved method and system for reducing the bandwidth requirements of satellite or wireless communication networks is described. In accordance with one embodiment of the invention, a training sequence is transmitted over a training channel from a terminal to a master station. The master station measures a frequency error of the training sequence, and provides the frequency error to the terminal. The terminal adjusts its transmit frequency by the frequency error, offsetting all further data channel transmissions by the frequency error.
