Abstract (in Japanese) (See Japanese page) 
(in English) A superposed transmission is one of the effective wireless communication schemes to improve the radio frequency utilization.
In this report, we propose the interference detection and suppression technique to mitigate the detrimental effect of unknown interference signals.
In this technique, the receiver estimates parameters of the interference from received signals using EM algorithm and decode the signals by weighing the LLR based on the estimated information.
