Patent ID: 7633923

Claim:
A transmission system for transmitting an information signal via a plurality of subchannels from a transmitter to a receiver, the transmitter comprising: a demultiplexer for demultiplexing the information signal into a plurality of information subsignals in dependence on a throughput of the subchannels as ordered by the receiver; an encoder for encoding input symbols of the information subsignals into output symbols such that k input symbols of the k-th information subsignal are encoded with a k×m-code into m output symbols, 1≦k≦m, said code having the following properties: all k input symbols and all m−k other output symbols are determinable from any k output symbols, and no m−l other output symbols are determinable from any l output symbols, l<k; a multiplexer for multiplexing the output symbols into output information subsignals; an interleaver for interleaving the output information subsignals; a channel encoder for channel encoding the interleaved output information subsignals into encoded information subsignals; and means for transmitting each encoded information subsignal via one of the subchannels to the receiver; the receiver comprising: means for receiving the encoded information subsignals; a channel decoder for successively channel decoding the received encoded information subsignals into channel decoded information subsignals by incorporating decoding information of already channel decoded information subsignals; a demultiplexer for demultiplexing the channel decoded information subsignals into channel decoded symbols; a decoder for decoding the channel decoded symbols into decoded output symbols and for supplying the decoding information regarding the decoded output symbols to the channel decoder; a further multiplexer for multiplexing the decoded output symbols into an output information signal.
