Iterative Detection and Decoding for Separable Two-Dimensional Intersymbol Interference

  author={Yunxiang Wu and Joseph A. O’Sullivan and Naveen Singla and Ronald S. Indeck},
We introduce two detection methods for uncoded two-dimensional (2-D) intersymbol interference (ISI) channels. The detection methods are suitable for a special case of 2-D ISI channels where the channel response is separable. In this case, the 2-D ISI is treated as the concatenation of two one-dimensional ISI channels. The first method uses equalization to reduce the ISI in one of the two dimensions followed by use of a maximuma posteriori (MAP) detector for the ISI in the other dimension. The… CONTINUE READING
