| Zusammenfassung: | A method and apparatus for adaptively controlling a transmission signal for transmission to at least one receiver in a terrestrial region is disclosed. The method selects a transmission signal mode having a modulation scheme, code scheme, and code rate from a plurality of transmission signal modes according to received information, generates a transmission signal according to the selected mode, and transmits the generated transmission signal to the receiver. |
