Abstract:
A method and apparatus to perform a soft demapping in a rotated quadrature amplitude modulation (QAM) based communication system is described. The method and the apparatus include pre-processing a symbol based on a priori information and performing a one-dimensional (1D) soft demapping on the pre-processed symbol, continuously.
