| Abstract(in English) | It is known that superposition modulation can generate a Gaussian modulated signal by superimposing a large number of signals.In this paper, we demultiplex the superimposed signals, which are copied several times in time domain, by using belief-propagation-based detection which is proposed for massive MIMO detection.Although simple multiplexing factors such as one or zero are easy to be implemented as a code book, degeneration in constellation is inevitable. Here, we evaluate the detection performance under some conditions for factor graphs and multiplexing factors. The simulation results show that reasonable performances can be obtained by setting unequal multiplexing number even in degeneration cases. |
