| Abstract(in English) | With the progress of IoT, the explosive increase in the number of devices connected to the Internet is predicted. Among multiple access techniques for the IoT, non-orthogonal multiple access (NOMA) has been attracted attention. Interleave division multiple access (IDMA), which is one of the NOMA techniques, specifies the transmitted data sequence using each unique interleave pattern. The NOMA allows interference between the users thus needs an interference canceller. In this paper, we consider to apply belief propagation with Gaussian approxi- mation for interference (GaBP) to detect IDMA signals and evaluate the BER performance. The simulation results show that GaBP achieves a good BER performance up to 32 users under the AWGN channel by using damping to reduce the vibration of LLR. |
