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:
- determining, by the receiving device, reliability ratings for undecoded data streams in a received transmission;
- selecting, by the receiving device, an undecoded data stream in the received transmission in accordance with the determined reliability ratings, thereby producing a selected data stream;
- decoding, by the receiving device, the selected 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 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;
- interleaving, by the transmitting device, the encoded data streams producing interleaved data streams;
- and
- transmitting, by the transmitting device, the interleaved data streams.
A receiving device comprising:
- a receiver configured to receive a transmission;
- and
- a processor operatively coupled to the receiver, the processor configured to determine reliability ratings for undecoded data streams in the transmission, to select an undecoded data stream in the transmission in accordance with the determined reliability ratings, thereby producing a selected data stream, to decode the selected data stream with a decoding trellis, thereby producing a data symbol, to update the decoding trellis in accordance with the data symbol, and to repeat the selecting, the decoding, and the updating for remaining undecoded data streams in the transmission.
