| Abstract(in English) | Non-orthogonal multiple access (NOMA) is considered to be a most promising next generation mobile communication systems. NOMA is more efficient than the conventional orthogonal multiple access (OMA) because it allows interference between information signals of multiple users to be multiplexed over a radio resource. Although a large amount of computational cost is required to remove interference, it is becoming possible to remove interference due to the recent improvement in computer performance. The sparse superposition codes (SSC) proposed by Barron and Joseph in 2010 is an error correction code that has been proven to achieve channel capacity in Gaussian channels. In this paper, SSC is used as a method of realizing NOMA. Of the multiple users existing in the base station, we will focus on the downlink lines of two users and investigate the interference elimination and decoding performance. At that time, an encoder and a decoder to which machine learning is applied in advance are used. We perform computer simulations and show the decoding error probability. |
