Abstract
A method, apparatus, article of manufacture, and a computer memory structure adaptively controlling a transmission signal from a satellite to at least one terrestrial receiver in a terrestrial region is disclosed. The method comprises the steps of receiving information describing a deleterious time-varying propagation characteristic of the transmission signal to the terrestrial region; generating the transmission signal having a transmission characteristic which mitigates the undesirable aspects of the time-varying propagation characteristic; and transmitting the generated transmission signal from the satellite to the terrestrial receiver. The article of manufacture comprises a controller device tangibly embodying instructions to perform the method steps described above. The apparatus comprises a receiver for receiving information describing a time-varying signal propagation characteristic of the signal to the terrestrial region; a signal generator for adaptively generating a transmission signal having a transmission characteristic mitigating the propagation characteristic; and a transmitter for transmitting the generated transmission signal.
