  • Using SISO decoder feedback to produce symbol probabilities for use in wireless communications that utilize single encoder turbo coding and transmit diversity
    Patent number: 7450672
    Abstract: An apparatus and method for transmitting and receiving a bit stream. On the transmission side, coded bits (Y.sub.t) and an interleaved version of the coded bits (X.sub.t) are separately modulated and transmitted. On the reception side, a priori output probabilities produced by a probability generator (34) are combined (112) and then input to a SISO decoder (111). Combined a posteriori output probabilities (115) produced by the SISO decoder are split (113) and then fed back to the probability generator.
    Type: Grant

  • Ordered decoding in wireless communications that utilize turbo coding and transmit diversity
    Patent number: 7099414
    Abstract: In a wireless communication receiver (31) of a wireless communication system that utilizes transmit diversity and turbo coding, symbol decisions are based at least in part on a posteriori probabilities (47, 48) produced by SISO decoders (35, 36). These probabilities are produced iteratively in alternating fashion to support the symbol decision process. The SISO decoder associated with the weakest (92) wireless communication channel goes first (93) in the iterative process.

  • Using SISO decoder feedback to produce symbol probabilities for use in wireless communications that utilize single encoder turbo coding and transmit diversity
    Publication number: 20020115463
    Abstract: In a wireless communication system, coded bits (Yt) and an interleaved version of the coded bits (Xt) are separately modulated and transmitted. On the receiver side, a priori output probabilities produced by a probability generator (34) are combined (112) and then input to a SISO decoder (111). Combined a posteriori output probabilities (115) produced by the SISO decoder are split (113) and then fed back to the probability generator.
