Abstract: The present invention involves a method for transmitting data within a specified band of allocated spectrum in a satellite digital transmission system. First a data stream is encoded according to a first encoding scheme, then a second data stream is generated according to a second encoding scheme. The second encoding scheme is incompatible with the first encoding scheme. The first and second data streams are transmitted at predetermined locations within the specified band, such as time slices within a time division multiplexing transmission system. The second data stream is generated by using a more efficient FEC algorithm, including turbo-convolutional, turbo-product, low density parity check, or repeat-accumulate encoders. The inventive receiver has an antenna for receiving RF signals and a demodulator coupled to the antenna for downconverting received RF signals into a data stream. A splitter then separates the data stream into first and second component data streams.
