Simplified Soft Output Demapper for High Order Constellations

The exact soft output demapper calculation for high-order constellations involves complicated operations. In this work, a method to simplify the soft output demapper, calculation is introduced. It is programmed to adapt as perfectly as possible the transmission system to the channel type in question. This method leads to simplifying the implementation of the transmission system. Also, it ensures efficient decoding regardless of the channel type.
