Abstract :
This paper presents a blind soft-output modulation decoder for signals transmitted wirelessly using any constellation configuration. The receiver algorithm operates by classifying the received symbols into probabilistically alike clusters which are ultimately used to estimate the underlying modulation constellation points and also soft information about the received signal.
