| Abstract(in English) | This paper investigates a methodology to apply code spreading to uplink single carrier non-orthogonal multiple access (SC-NOMA) for massive connectivity. In massive connectivity as one of the fifth generation telecommunication systems (5G) requirements, massive devices transmit less data by low data rate. In such a case, it is important to realize sum-rate throughput of multiplexed devices near channel capacity in order to efficiently accomodate massvie devices. In this paper, assuming multi-user detection by turbo equalizer, we study code spreading to increase the available number of multiplexed devices for SC-NONA where signals are spatially overloaded. This paper applies orthogonal code or repetition code to SC-NOMA as a method for spreading code. Computer simulations show performances of SC-NOMA with code spreading. |
