Abstract
A method for operating a receiving device includes determining reliability ratings for undecoded data streams in a received transmission, selecting an undecoded data stream in the received transmission in accordance with the determined reliability ratings, thereby producing a selected data stream, and decoding the selected data stream with a decoding trellis, thereby producing a data symbol. The method also includes updating the decoding trellis in accordance with the data symbol, and repeating the selecting, the decoding, and the updating for remaining undecoded data streams in the received transmission.
Claims28
A method for operating a receiving device, the method comprising:
- receiving, by the receiving device, a plurality of faster than Nyquist (FTN)-rate undecoded data streams having different reliability ratings, in a received transmission;
- determining, by the receiving device, the reliability ratings for the plurality of FTN-rate undecoded data streams in the received transmission;
- selecting, by the receiving device, one of the FTN-rate undecoded data streams in the received transmission in accordance with the determined reliability ratings, thereby producing a selected FTN-rate data stream;
- decoding, by the receiving device, the selected FTN-rate data stream with a decoding trellis, thereby producing a data symbol;
- updating, by the receiving device, the decoding trellis in accordance with the data symbol;
- and
- repeating, by the receiving device, the selecting, the decoding, and the updating for remaining FTN-rate undecoded data streams in the received transmission.
A method for operating a transmitting device, the method comprising:
- receiving, by the transmitting device, a first data stream and a second data stream;
- independently encoding, by the transmitting device, each data stream, wherein the independently encoded data streams have different reliability ratings;
- interleaving, by the transmitting device, the independently encoded data streams, thereby producing interleaved data streams;
- and
- transmitting, by the transmitting device, the interleaved data streams as faster than Nyquist (FTN) rate data streams in a transmitted transmission.
A receiving device comprising:
- a receiver configured to receive a plurality of faster than Nyquist (FTN)-rate undecoded data stream having different reliability ratings, in a received transmission;
- and
- a processor operatively coupled to the receiver, the processor configured to:
- determine the reliability ratings for the plurality of FTN-rate undecoded data streams in the received transmission,
- select one of the FTN-rate undecoded data streams in the received transmission in accordance with the determined reliability ratings, thereby producing a selected FTN-rate data stream,
- decode the selected FTN-rate data stream with a decoding trellis, thereby producing a data symbol,
- update the decoding trellis in accordance with the data symbol, and
- repeat the select, the decode, and the update for remaining FTN-rate undecoded data streams in the received transmission.
