Publication number: 20060029169Abstract: 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: ApplicationFiled: October 7, 2005Publication date: February 9, 2006Inventors: Alan Gatherer, Tarik Muharemovic, Everest Huang, Srinath Hosur
