Turbo-coding DOCSIS information for satellite communication |
摘要 |
Methods and systems for modifying DOCSIS-based transmission paths for communication in higher frequency and/or wireless environments, such as wireless terrestrial communication systems and satellite communication systems. An inner turbo-code is combined with a DOCSIS based Reed-Solomon ("RS") forward error correction ("FEC") coding scheme, to produce a concatenated turbo-RS code (other FEC codes can be utilized). In phase and quadrature phase ("I-Q") processing is utilized to enable relatively low cost up-converter implementations. The I-Q processing is preferably performed at baseband, essentially pre-compensating for analog variations in the transmit path. Power amplifier on/off control capable of controlling on/off RF power control of remote transmitters is modulated on a transmit cable to reduce the need for a separate cable. |
