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.

基于超可靠和低延迟的通信辅助调制的非正交多址方案

技术需求非常需要物联网(IoT)执行。当然,它将带来从本地城市到智慧城市的范式转变。除了其他几个应用之外,智能交通系统(ITS)将带来占主导地位的智能社会转变。ITS将使不断增长的交通系统安全性,可靠性,需求和安全性受益。由于大数据和流量需求,使用ITS可以实现5G超可靠和低延迟通信(URLLC)合并。在本文中,我们取消了针对5G的超可靠和低延迟通信(URLLC)用户案例的基于调制的非正交多路访问(M-NOMA)技术支持。然后,我们将其作为ITS的用例进行介绍。M-NOMA的最小符号错误率(SER),减少的干扰,更高的数据速率,从而提高服务质量(QoS)。在本文中,我们推导了具有加性高斯白噪声(AWGN)和衰落信道的M-NOMA的SER。我们还使用拉格朗日优化技术优化了导出的SER和数据速率。所提出的系统支持低等待时间和高可靠性要求。仿真结果证实了我们的M-NOMA方案比传统方案具有更多的好处。
