An ultra-reliable and low latency communications assisted modulation based non-orthogonal multiple access scheme

Abstract

The technological demand drastically requires Internet of Things (IoT) execution. Certainly, it will bring a paradigm transformation from a local city to a smart city. Besides several other applications, Intelligent transportation system (ITS) will bring a dominant smart society shift. ITS will benefit growing traffic system safety, reliability, demand and security. 5G Ultra-Reliable and Low Latency Communications (URLLC) amalgamation is certain with ITS due to big data and traffic requirements. In this paper we demontrate our Modulation based Non Orthogonal Multiple Access (M-NOMA) technique support for Ultra-Reliable and Low Latencey Communication (URLLC) user case of 5G. Then we present it as a user case for ITS. M-NOMA guarantees reliability and low latency of the system due to its minimum symbol error rate (SER), reduced interference, better data rate and hence the Quality of service (QoS). In this paper, we derive SER for M-NOMA with Additive White Gaussian Noise (AWGN) and fading channel. We also optimized the derived SER, data rate with Lagrange optimization. The proposed system supports the low latency and high reliability requirements. Simulation result confirmed the added benefits offered by our M-NOMA scheme over the traditional schemes.
